加拿大3G的制式是什么?

 加拿大地区3G网络所使用的制式是什么啊?跟中国一样么?也是cdma?还是其他的?高手快来啊!

 
 WCDMA和联通的一个样!

       移动TD-SCDMA(TDD):

  • 核心频段:1880~1920MHz,2010~2025MHz

  • 补充频率:2300~2400MHz

  联通WCDMA(FDD):

  • 核心频段:1920~1980MHz,2110~2170MHz(分别用于上行和下行)

  • 补充频率:1755~1785MHz,1850~1880MHz(分别用于上行和下行)

  电信CDMA2000(FDD):

  • 核心频段:825~835MHz,870~880MHz(分别用于上行和下行)

  • 补充频率:885~915MHz,930~960MHz(分别用于上行和下行)

----------------------------------------


 850/900/1800/1900这个是3G的频率吗?

不是。是传统GSM网络。

例如:

移动的GSM网络(FDD):

  GSM 900:

  • 上行(移动台发,基站收)899~915MHz

  • 下行(基站发,移动台收)944~960MHz

  GSM 1800:

• 上行(移动台发,基站收)1710~1785MHz

  • 下行(基站发,移动台收)1805~1880MHz

---------------------------------------------------------


 Rogers 是加拿大最大的GSM无线电话商, 用的是GSM 850MHZ 和 GSM 1900 MHZ,    FIDO 一年前已经被 ROGERS 收购, 用的是 GSM 1900MHZ.      TELUS 和 BELL 都是 CDMA 网络, 手机没有 SIM 卡也没有 USM 卡的.       中国的手机如果要保证在加拿大能用至少要有 1900MHZ, 如果没有 850MHZ, 在地下停车场\隧道\电梯间会接收不到信号, 所以建议最好用四频手机.       中国的手机大多是两频或者三频, 低端手机里面四频的比较少见, 智能手机比如 HP iPAQ6515/6955 \Treo 650/750 Blackberry 7100/8700/8100/8800 HTC s620 都是四频的...      加拿大的 Rogers 不用 WCDMA/CDMA2000, Rogers 的 3.5G 手机是 HSDPA, 所以不要买中国或者香港的 3G 手机到这边用(用不上,浪费)      如果要用 email 的话建议买带有 Wifi (802.11 b/g) 的手机, 有急用的话在有免费wifi的地方就可以收发电邮      加拿大的本地手机很少有中文(不排除海外水货有), 所以不喜欢用英文机最好还是自己带.         加拿大的手机服务相对比较便宜, 一般接听免费(国内所谓的单向收费)的计划是 $25~35, 加上$6~8的牌照费, 911费, 来电显示费...一般月租在 $30~50, 如果签上3年的合同就可以拿商家送的手机   所谓的合同就是卖身契, 每个月用要给钱不用也要给钱是也.    如果签了最低的约, 比如$20每月, 加上杂费和税之后每月支出如果按照 $37算, 一年就是 $37 x 12 = $444, 三年就是 $1332.    如果不超支, 基本上就是那么多. 所以回头看送手机只不过是服务商的揽客手段之一.

Google Goggles 的奥秘

http://www.guao.hk/tag/google-goggles

09年最早出现在 Android 上,不久前登陆 iOS 平台的 Google Goggles 是一个非常有意思的应用,可以让你拍张照片就对里面的物体进行搜索,其最新版甚至还能帮你解开数独谜题。其实 Google 还隐藏了一个秘密:你所有在 Goggles 里面搜索过的图片 Google 都偷偷帮你记着呢,只要进入这个页面你就可以看到了。好心的 Google 还贴心的提供了 Remove Items 的功能,赶快把你搜索记录中见不得人的图片都删了吧。

另外可以想象的是,未来 Google Goggles 的搜索历史也会和 Web 搜索历史以及图片搜索等功能结合在一起,甚至允许用户直接在 Web 上直接提交 Goggles 搜索也说不定。

Top 10 SEO Tips for New Websites

http://www.devx.com/DevX/Article/46214/1954?pf=true

Top 10 SEO Tips for New Websites

Neophyte sites should be realistic in their goals, focus on building trust and crank up the social media campaign.
Every site needs to attract attention. Since people can only come to your site by typing your URL directly into the browser, come to your site from a link on another site another, or find you via a search engine, the topic of getting traffic from search engines is a very important one. In this article, we'll go over SEO (Search Engine Optimization) strategies that many new sites would do well to follow to grow traffic to their sites.

1) Lower Your Expectations

New sites have very little trust, no authority, few pages, and very little unique content. There is absolutely no way that new sites can get high levels of traffic from SEO or rank in the top-10 for high-volume and competitive searches. One your site is trusted, you can produce content and see your new pages in the top-10 or top-20 of Google search results withing a few days or less. Unfortunately for new sites, it takes much longer to achieve high rankings in search engines. New and untrusted sites without much authority must take to heart the old "it takes six months for SEO to work" approach.

Instead of hoping for immediate results, new sites must instead focus on making long-terms plans. There must be a plan to build trust and authority in their niche, consistently create optimized content, and a great overall product to which people will find it natural and helpful to link.

If you expect strong SEO traffic in the first 6 months of your site's existence, it is not going to be easy to accomplish. You may want to rethink your initial goals and lower the expectations from SEO until your site is trusted and has built up some authority.

2) Focus on Building Trust

New sites are given a little bit of trust by search engines, but the amount of trust new sites have is not enough to rank for any significant terms. Trust has to be built. There are a number of ways to make a search engine view your site as trustworthy. One such way is to maintain good practices of content creation. You must consistently create new content that is good enough to earn links on its own. We will touch on content creation in more detail a little later in the article.

Another great way to build trust is to get sites that are big and already trusted to link to your site. There are many types of trusted sites. Links from sites that belong to universities (.edu domains), non-profits (.org domains), or large companies can carry quite a bit of trust with them. In a search engine's mind, if a university (usually professor or student page) trusts you enough to link to you, then it is much more likely that your site can be trusted, and will likely rank higher.

3) Aim for Long-Term Authority

Since at the beginning you will not be seeing much SEO traffic, but instead focusing on long-term plans to be an SEO giant, one great strategy is to become an authority in some niche. If you become an authority in a niche, you will earn links when other webmasters will need to link to credible sources and will link to you. When search engines see many consistent new links into a site, the search engines begin to think that this site has authority and authority is one of the biggest single determining factors in the rankings of pages within search results.

Unfortunately, if you are like most sites, you don't and won't have real authority. It is up to you to make this into a non-problem. You can mimic authority. One way to get many links into your site is to provide some widget or an embed tag that lives on other sites. Since every time someone uses your widget that is hosted on your site, it also creates a link to your site, over time this will create an appearance of authority when many sites link to you just by using your widget.

It isn't easy to get a widget or embedded content to become so popular that many sites will use it, but it is good to think about this early because if you do manage to create something that useful, it will pay off incredibly in the long run.

4) Create Content

Content creation is a really important topic for all sites. There are three main considerations when creating an SEO-driven content creation strategy: 1) You must be as prolific as possible in your content creation. 2) You must balance the speed with which you create content with the highest possible quality of that content as possible. 3) You must also have an effective and cheap content promotion strategy beyond SEO, and a link-building strategy for the content you produce.

Since this article focuses on SEO, try to write content that is likely to attract links on its own. Such content is usually written to a high level of literacy, and is over at least 300 words per page (more is often better) of original content. If possible, the content should have a mechanism to keep itself fresh. That is done by letting the users control the content on a part of that page.

That way you have the high quality content you wrote yourself and another part of the page that is kept fresh by users who make your page have increasingly more content.

I probably should not have to say that your content should be original, but it must be repeated many times. Write original, compelling content. If you copy content, search engines will eventually detect that and will penalize you by removing your pages with copied content from the
search engine rankings all together.

5) Build Inbound Links

This is obvious, but you have to focus on continuously building links into your site. There are a few strategies and guidelines that you should follow in order to not look suspicious. In general, your link creation should look as natural as possible to create the appearance though you earned these links without trying.

To make the links that come into your site look natural, aim for moderation in everything. For example, if you have many exchanged links (a situation where you link to a site that also links to you) that looks unnatural. But also, if you have no exchanged links it looks unnatural as well since it is pretty natural for sites in the same niche to link to each other and a little bit unusual if a site has no links to and from other similar sites.

When discussing link building into your site, there is also the dirty work called "link begging." It is one of the least attractive SEO practices, but it is necessary to some degree. What you do is email a few hundred respectable and highly reputable sites in your niche and politely ask if they would link to you. Depending on the quality of your site you will have a 1% to under 10% success rate. If you have a new, recently launched, or a somewhat non-professional looking site, expect to have a link begging success rate of very low single digit percent. But if the sites you email are reputable, the very few links you will get will go a very long way in helping you grow trust in the eyes of search engines. Often, a few great links is better than thousands of low-quality links.

Of course, there are a number of ways to make your link begging success rate rise, but that depends on your creativity, savvy, and resourcefulness. And of course, the biggest determining factor in your link begging efforts is the quality of your site and product. So as your site matures, people will take notice and be more willing to link to you.

6) Build Social Media Presence for SEO

Social media is not traditionally discussed in the same conversations as SEO, but that is changing. Google is now crawling tweets, and search engines are also developing other ways to determine whether a site is strong in social media, and using that as a factor in determining the overall quality of the site.




Just as links are a sign of popularity among websites, social bookmarks are signs of whether real people using the Web are showing signals of approval or indifference towards various pieces of content.

The important factor in considering social media when thinking about SEO is that there are no signs that the role of social media on the Web is declining. If anything, the Social Web is growing in prominence and in order to maintain search quality, search engines will need to pay attention to the social side of the Web. Additionally, actions of immediate friends are going to gain importance, so having a large social reach will likely reflect positively on SEO results.

7) Cross-Linking Strategy

Some of the easiest inbound links for a new site to get are ones where you also link to the person who is linking to you. It usually requires some communication between the webmasters of the two sites and an agreement to link to one another and make the links permanent.

Since it is difficult to obtain most links from coveted and trustworthy sites, it is easy to get carried away exchanging links with other new or unestablished sites just because of the comparative ease of obtaining the links in link exchanges.

Link exchanges are much less effective now than they used to be in the past, but they still work to a lower degree. A savvy link-exchange campaign can give you one of the best boosts when your site is still new just because many of the other methods of obtaining links are just too tough for new sites to pull off. When you do exchange links, only do so with sites in your niche that are reputable and trustworthy. Refrain from interlinking with other unestablished sites because more often than not you will just end up in bad link neighborhoods which can actually cause you SEO damage instead of benefit.

8) Linking Out Strategy

SEO is a strange field where there are often conflicting answers to many questions. One of the biggest points of confusion that many new site owners encounter is what their strategy should be for linking out to other sites.

Most new sites try to hoard the little amount of link juice that they have and not link out, but that is often a very limiting and unnatural approach. Since it is difficult for a new site to get other sites to even work with them, new site webmasters should feel very free and open about linking out (as long as those sites are of high quality) in an attempt to participate in as many initiatives as possible and to forge many relationships with as many people in their niche as possible.

Most of the time, a relationship is worth much more than a link. So if you review other prominent sites or just link to them and tell them about how much you like their sites and inform them of the link you posted, moving forward it might make them friendly towards you, and you will likely be able to count on many little favors from them along the way. That favor may come in many forms. It may be a link, a Facebook "like," or a powerful stumble or a an introduction to someone who can help your site.

The same linking philosophy is true when it comes to linking out to social networking sites or embedding interesting pieces of content from other sites into yours. While you don't want to go too far with linking out, if the link you may put on your site decidedly enhances the experience of your users, you should probably add that link. You should add such a link especially eagerly if it is to a reputable site.

9) Minor On-Site Tips and Tricks

To battle the link scarcity from the outside, you can do things within your site to create more links to your pages and get those pages ranking for various terms faster than they would if you had just waited.

You must have a strategy to interlink your internal pages. Content pages should link to other pages using the Wikipedia style within-content links. These are the most natural looking internal links, and will carry most weight. Second, you should have sections for related topics where you can add links to pages within your site which you would like to make more prominent. Third, you can have a table of contents section.

The table of contents within a content page creates links to that very same page. Here is an example of how to do this: In your table of contents section you can have links like I made on this Muir Woods Hiking page:

Take a look at the left side of that page after the navigation. There is a table of contents there. Each link in the table of contents goes to a section of that very same page. Here is an example of an HTML link for creating one of these table of contents links:

Muir Woods Wildlife.

The subsection HTML also looks slightly different. Here is the example of the HTML for the actual subsection:

<a name="muir_woods_wildlife"><h2>Muir Woods Wildlife</h2></a> 
Notice the extra #muir_woods_wildlife at the end of the URL. That is the instruction to point to a subsection of the HTML. The subsection HTML also looks slightly different. Here is the example of the HTML for the actual subsection:
 <a name="muir_woods_wildlife"><h2>Muir Woods Wildlife</h2></a> 
Take a look at how the Muir Woods page uses the in-text links to other pages, table of contents, and a related topics section to make the most out of the internal links it can have.

10) Keeping Sight of the Bigger Picture in SEO

Simply ranking in the top 10 or top 5 search results for competitive search terms can be very lucrative on its own. There are even numerous highly successful companies who do only one thing: rank pages in the top 10 for various competitive search terms. Yet for most companies, the effort that it takes to get into the top 10 is not worthwhile unless there are secondary goals.

Secondary goals may be to sell goods or services, or get people to make accounts on their sites, etc. A very important distinction that webmasters should always keep in mind is that some search terms may be highly converting (get the users to do what the webmaster wants them to do) and some search terms that seem like they should convert, do not.

Keeping with the example above with the hiking site, I had originally theorized that if I optimized the site for various hiking spots around the Bay Area (the site is a local for the San Francisco Bay Area) that people would convert into signed up users at a pretty high rate.

Once I got a number of pages ranking high for such terms, I was able to track that these users were actually not converting and not signing up. They just read about hiking at parks and left my site.

What gave me the best conversions were searches like "group hiking in San Francisco." That might be an obvious point since the site is about group hiking in the Bay Area, but there are just not that many such searches overall, so I could not rely on those searches alone.

So when you are embarking on a long-term SEO campaign, keep in mind what conversions you eventually want, and how to get them in a high-enough volume.

Also make sure that your site will actually be capable of ranking in a top-10 for some searches. Some high-volume search terms are very competitive and are nearly impossible to break into. You don't want to see your site stuck on the 3rd page of search results after months of trying to get it to rank.

Bonus Item: Build Videos (Advanced)

Traditional SEO has mostly been centered about written content. Yet more and more the content on the Web is in video form rather than written in text. What some people do is make videos and maintain their own channel on YouTube that parallels their on-site content strategy. That way they can embed the video into their blog with their written text. This results in a fuller engagement of the users with the sites' brand.

From the blog, users can click on the video channel and then see the related videos in your channel, leading them to spend more time surfing content from your brand or site. This longer engagement of the user with your site often leads directly to higher levels of conversion. Additionally, many people believe that having text, photos and videos on your page makes the page appear more "interesting" in the eyes of search engines which see it as you offering more content to your users, and rank you higher since they perceive that as potentially being a higher quality page.

手机GSM900/1800MHz和GSM 850/900/1800/1900有什么区别?在国内使用有什么问题吗?

http://wenda.tianya.cn/wenda/thread?tid=41493065d0286469

提到手机支持频段,首先应明确频段实质上是硬性划分的,这主要是由于频率资源的有限导致, 目前我国主要由信息产业部负责相关事宜。

我国手机常用的频段主要有CDMA手机占用的CDMA1X,800MHZ频段;GSM手机占用的900/1800/1900MHZ 频段;近两年的GSM1X双模占用的900/1800MHZ频段;3G占用的900/1800/1900/2100MHz频段。

GSM频段:我国GSM手机占用频段主要是900MHZ和1800MHZ。实质上1800MHZ也是由于手机用户数量 的激增,造成了手机通信网络系统处于超负荷运转状态,最终导致了手机在通信时很容易出现类似于 掉线、串音、话音质量不好、难以上网等故障现象。为了解决这些故障现象,越来越多的手机运营商 和生产商开始意识到解决这个问题的迫切性,并不断采取相关措施来进一步扩容手机网络系统,于是 GSM1800Mhz便应运而生了,又被称为DCS1800(数字蜂窝系统),它的出现,使基于GSM900、1800的 双频网络变为现实。

使用GSM900/GSM1800双频手机,用户可以在GSM900与GSM1800之间自由切换,可以有效地避免以 往掉话,通话难和音质差等问题,较以前只使用GSM900网的通话更加方便。

所谓的"三频"就是包含3个工作频率,这三个工作频率就是GSM900Mhz、DCS1800Mhz以及 PCS1900Mhz,依此类推,所谓的"三频手机"就是指手机可以同时接收GSM900M、DCS1800Mhz以及 PCS1900Mhz这三个频率段的信号,从中做出选择,那一频段的的信号强,就选择那一基站的信号, 如果一方接不通,可以自由转到别一个频段的信号上。它实际上就是扩大了手机的接通率。在一些手 机用户比较集中的地区,尤其合适使用三频手机,因为三频手机能够灵活地在GSM900、DCS1800和 PCS1900之间进行切换,以便始终保持通话不断及通话质量。PCS1900兆网,是北美地区(美国、 加拿大)及欧洲国家通信网络领域普遍使用的网段。

由于三频手机能同时工作在三个不同频率的网段之中,因此三频手机无疑具有这三种网络的特点。 从技术角度而言,GSM1800因为频段高,使得信号穿透能力强,因此在高楼林立的复杂环境中能带来 良好的通话质量和通信覆盖;而PCS1900频道,在北美地区(美国、加拿大)及欧洲地区有着良好的 通信能力,这无疑为那些频繁来往于洲际间的人士提供了他们所需要的服务。

Top 20 Open Source Applications to Cut Business Costs

http://itmanagement.earthweb.com/osrc/print.php/3919961
— Datamation.com

By Matt Hartley
January 10, 2011

In this economy, employees who can save their employers money are highly regarded and will potentially be in line for advancement. Using open source technology is one great way to help your company cut down on costs across the board.

In this article, I'll share twenty great open source applications that can help save your employer some money.

1) eZ Publish: Rather than paying a small fortune for a decent Web Content Management System, why not look to eZ Publish instead? Designed to work with businesses needing to push out multiple channels of content easily, eZ Publish takes it one step further with one of the best portal/front page management solutions available in the open source space.

2) Talend Open Studio: Managing data is more than mere content management, CRM or working with databases. These days, there is business modeling, graphical development and real-time deployment issues that must be considered within the modern enterprise realm. Even more importantly, there needs to be an effective software suite that allows the end user to roll all of this up into one usable tool. Talend Open Studio is one potential solution that, based on its feature set, might be the perfect fit for a business in need. Data integration, data migration and data synchronization operations are all things addressed by this software suite.

3) KnowledgeTree Document Management System: Despite Google Docs being all the rage for many growing businesses these days, there's still enough concern over privacy that other businesses are looking into open source alternatives. Note that I'm not talking about Open Office/Libre Office here, but rather a solution that has many of the advantages one might find with the collaborative goodness of Google Docs.

The cleverly named Knowledge Tree provides its users with all of the collaborative tools a company might need, while allowing the enterprise user the freedom to either use their pro version or host it themselves. Some advanced features, however, may not be available in the community edition.

4) Wordpress MU: Designed to provide the ultimate blog platform for a multiple user base situation, many companies may find that using Wordpress MU is the perfect tool to get enterprise level content creation to become a regular part of the work week.

And thanks to the recent blending of MU (Wordpress multiple user) with the main Wordpress project, you'll be seeing the blogging platform updated more frequently now. This sits well with both the functionality and security in running a strong multiple user friendly CMS.

5) Pentaho: When it comes to analyzing business intelligence there is a baffling multitude of options. What's worse is seeing businesses paying absorbent amounts of money in licensing fees just to run these applications. Stop and consider going with Pentaho instead. It offers integration, analysis and reporting all from one suite, available in an open source package.

6) SugarCRM: Customer relationship management (CRM) is a great tool because in today's workplace, working through customer relations effectively is more critical than ever. But rather than forking over funds for software that isn't that great in the first place, why not get the same functionality from an open source alternative like SugarCRM?

And like most open source enterprise software, you can pay as much or as little as you choose. Want to go at it alone? SugarCRM allows for this with a zero-cost download. Want to run with some professional functionality? Again, you can choose a pricing package that meets your companies needs instead of the typical one-price-fits-all kind of approach.

7) Zencart: So many businesses these days are working within the e-commerce space that having the right tools in place is among the most important things to consider. This is why using a product like Zencart makes more sense than going it alone. You may start out paying for the service, only to later run the show yourself with this open source solution.

Again, the freedom of software using the open source approach is very empowering. This is especially true if you want to take something Zencart is doing, make it better and run it on your own terms. Complete with plenty of great add-ons to further extend functionality, Zencart is a great place to start in handling your company's e-commerce needs.

8) Eucalyptus: Tired of waiting for someone else to run web services the way you need them to work? Fine, take Eucalyptus and make it happen yourself for your own company. You'll be able to put your company's software into the "cloud" while maintaining control of how it happens – while not bowing to Google or Microsoft in the process.

9) Zenoss: Systems management doesn't have to be a private, proprietary affair. No, in fact you can use trusted, controllable open source software from Zenoss instead. The basic idea behind this tool is that you should have one suite of tools to handle systems management, rather than dancing between half a dozen just to do the same job.

10) Asterisk: Using a proprietary solution PBX system to handle communications is becoming terribly inefficient from a cost perspective. Even with the collective cost of support in using open source options, you will end up with a more adaptable setup using a PBX product like Asterisk rather than something proprietary based.

Obviously the ideal setup is having the right support for your Asterisk system in-house, but even if you don't, you can shop around for the best price if support should become necessary. With proprietary solutions, perhaps not so much.

11) Vicidial: Asterisk is very powerful and makes for a strong PBX product, but there are some fantastic add-ons that can make it even better. Vicidial is one such example. Designed to make predictive calling affordable, Vicidial is nice because it fits nicely into the existing communication structure, rather than trying to layer together a few different expensive proprietary products.

12) Openproj: There are always a variety of open source options for virtually any enterprise application you can think of. Project management software is certainly no exception to this rule. Openproj is one such solution and, despite its recent acquisition from Serena Software, it's said that Openproj will continue to be made available to all who are looking for a strong project management suite.

13) Openmeetings: It seems that acquisitions are in the air right now, with another open source meeting solutions being bought up by Salesforce. Luckily, Openmeetings is still free from this trend and, unlike DimDim, it's not tossing their users out like yesterday's newspaper.

What makes using Openmeetings so exciting is its embrace of other open source solutions like Moodle and SugarCRM. This means that conducting meetings that involve contact info or scheduling can be done easily, thanks to some forward thinking from the developers.

14) MediaWiki: If you're looking to run a wiki for your company and would like to use the same kind of functionality found with the Wikipedia project, then I 'd suggest you take a hard look at MediaWiki. Known to be the nuts and bolts behind the super-successful portal Wikipedia, MediaWiki is easily among the best of the open source Wiki solutions available today.

15) LimeSurvey: Simple, yet very powerful and effective is how I would describe the open source LimeSurvey software. It makes creating an open source enabled online survey relatively simple. Rather than fighting with ad-filled, sloppy alternatives, LimeSurvey ensures you're not potentially infecting your customers with questionable code or malware of some sort.

16) OpenBravo: Said to be among one of the best ERP (enterprise resource planning) software suites available, OpenBravo allows you to dedicate your funding to other mission critical projects and leave the ERP stuff to this solid open source option. This software suite comes complete with built in Integrated Accounting, Sales & CRM, Procurement, Inventory, Production, and Project & Service Management solutions.

17) Ekiga: "Skype for SIP fans" is how I've heard Ekiga described by some of its fanbase in recent years. Definitely the strongest Skype alternative I've ever used, I also love the fact that it works extremely well when used over a LAN. So you can communicate with others in the office, in addition to using its Skype-like functionality.

18) Dolphin Smart Community Builder: Rather than placing the your social networking needs into the whims of Facebook or Twitter exclusively, consider adding Dolphin Smart Community Builder to your social media strategy. The software is perfect for creating and managing dating sites, social networking portals and other similar niche communities where your company is in complete control from Day One. This is much more than a mere social media tool – it's a full-on community building software.

19) Compiere Community Edition: Because it never hurts to include more than one ERP suite in a list like this, Compiere Community Edition is a good alternative for any company not interested in using OpenBravo. Despite the push for buying the paid edition(s) of the software, Compiere's community edition does provide quite a bit of ERP functionality that users need within the enterprise realm.

20) Otrs: Like most concepts in the open source help desk area, it's safe to say there is never a silver bullet here. But for what it's worth, I think that Otrs is pretty darned close to being perfect for the needs of most companies. What makes using Otrs so powerful is that this is much more than mere help desk software. It also provides for sales/pre-sales support, billing and internal IT support as well.

  对于Android用户来说,建议另一个Twitter客户端:Twidroyd,也是一个很好用的Twitter客户端,而Twidroyd支持自定义API,使用这个应用可以很方便的上Twitter,效果很不错。Android下的Twitter客户端Twidroyd使用方法是,先用Twip建立一个基于OAuth的API,然后在这个API上登录Twitter帐号,保存一个新的登录密码,之后在Twidroyd下使用这个API,用Twitter的用户名和保存的新密码即可登录,在手机上不需翻墙。(注:我的Twitter)

  Android用户无法使用Instagram,也不必灰心,Android平台有一个和Instagram非常类似的应用PicPlz,Android手机用户可以使用这个类似的服务来实现社会化照片,PicPlz也可以让用户通过手机快速地将拍摄的照片分享到各个社会化网络,用户可以用PicPlz拍摄的照片发布到PicPlz的用户主页,也可以将其同步到Facebook、Twitter、Foursquare等社交网络上。PicPlz即支持iPhone,又支持Android,还支持从电脑浏览器访问,用户甚至可以将自己用相机拍摄的照片上传到PicPlz网站。(注:我的PicPlz)

  社会化音乐

  Last.FM

Last.FM

  Last.FM是全球最大的社会化音乐平台,通过用户的音乐收听情况提供个性化推荐、提供定制的电台广播等服务。用户只要在自己的电脑上安装一个客户端软件Scrobbler,此后用户在iTunes等播放器上收听的音乐都会被忠实地记录下来,Last.FM会分析哪首歌曲播放的次数最多,然后自动向用户的个人音乐主页添加数据,推荐用户可能喜欢的新音乐。iPhone版本的Last.FM是一个音乐电台播放器,用户登录之后,可以在联网的情况下播放自己的历史音乐或者LastFM推荐的音乐电台。类似的音乐电台应用Pandora(潘多拉)效果也不错,不过Pandora已经屏蔽了美国之外的用户访问。(注:我的Last.FM)

  豆瓣电台

豆瓣电台

  豆瓣电台是豆瓣网推出的一个类似Last.FM的社会化在线音乐服务,用户可以使用浏览器在豆瓣电台收听个性化音乐,移动客户端支持iPhone和Andriod,豆瓣电台包括"喜爱、丢弃、跳歌"等功能,系统通过判断用户在播放时的操作行为,为用户推荐他可能感兴趣的曲目。豆瓣电台没有客户端软件Scrobbler,因此无法自动记录用户在客户端收听的歌曲。(注:我的豆瓣)

  虾米

虾米

  虾米是另一个类似Last.FM的社会化在线音乐服务,提供较高品质的音乐,支持客户端记录软件,移动版支持iPhone和Andriod,可以管理已经离线的歌曲,让用户在没有网络的时候也可以听音乐。(注:我的虾米)

  总的来说,目前Android在社交应用领域已经接近iPhone,大部分常用的社交应用都同时支持iPhone和Android,不过在游戏方面,Android面对iPhone的还是依旧处于弱势状态。
