我在使用Android手机的时候，经常会出现这样的现象，平时GPRS上网没问题，但是用过WiFi后切换回GPRS网络，切换到GPRS后有图标但连接不上网络了，在海卓APN开关里重新关闭并打开GPRS，甚至重新设置GPRS，都无法解决这个问题，只有重新启动手机之后，GPRS才能正常连接。
GPRS连接不上的现象是，GPRS/EDGE的"E"标记是有的，左右两个上下箭头，只有向上的上行箭头亮，右边那个下行的总是灰色的，网络连接长时间无反映，最后显示无法连接网络。
最终在一些论坛找到了解决这个问题的方法：
在手机拨号中输入: *#*#4636#*#*
点手机信息，拖动到最下面，有个选项是"切换DNS检查"，点击将里面的内容切换成 0.0.0.0 allowed (这一步很关键)，之后重启手机，GPRS网络就正常了。
With so many different resolutions (800x600, 1024x768, etc.), browsers (Internet Explorer, Firefox, etc.), and platforms (Windows, Mac, Mobile ,etc.) in use, it is very difficult to design a page that looks good (or at least looks the same) in all configurations.
To design a page that looks good with most configurations, let's start by defining our main objective: we must never force a user to scroll horizontally. In other words, our page must always fit within the available screen width. This would suggest that we have to design our page for the lowest common denominator.
| January 2010 | |
|---|---|
| Resolution | % of Total |
| 1280x1024 | 18.2 % |
| 1280x800 | 17.3 % |
| 1440x900 | 10.5 % |
| 1680x1050 | 10.0 % |
| 1920x1200 | 4.6 % |
| 1366x768 | 3.6 % |
| 1920x1080 | 2.3 % |
| 1152x864 | 2.1 % |
| 1600x1200 | 1.4 % |
| 1280x768 | 1.2 % |
| Other | 4.8 % |

Should we design a fixed-width page, or should we specify the width of our page in percentage terms?
fixed-width: There are pros and cons for both. The main advantage of a fixed-width page is that the layout will always remain as you intended, even when viewed at higher resolutions. The main disadvantage is that users with larger screens, set at higher resolutions, will not be able to fully utilize them, and will instead see large, unused blocks of space around your page.
percentage terms: The advantage of establishing our page width in percentage terms, as 100%, is that the page will adjust itself to the resolution of the screen. This is called a "liquid page design". The main benefit of this method is that all the available screen real estate will be utilized. The disadvantage is that the layout of your page will change, and users may find it uncomfortable to read the extremely wide sentences that will result when higher resolutions are used.
If you decide optimize your page for 1024x768, and then decide to follow the fixed-width page method, you must take into account that not all the 1024 pixels will be available (some of them will be used by the browser to display the scrollbar and other "browser chrome"). To accommodate most browsers and platforms, specify your page width at a maximum of 960 pixels.
If you decide to specify your page at 100% width, you won't have that problem, since it will adjust automatically to the available width. Just make sure that your page looks best at 1024x768, and that the layout doesn't change much when you view your page at 1280x1024.
The Tianhe-1A supercomputer is about 50% faster than its closest rival.
China has claimed the top spot on the list of the world's supercomputers.
The title has gone to China's Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.
To reach such high speeds the machine draws on more than 7,000 graphics processors and 14,000 Intel chips.
The claim to be the fastest machine on the planet has been ratified by the Top 500 Organisation which maintains a list of the most powerful machines.
High powerChina's Tianhe-1A (Milky Way) has taken over the top spot from America's XT5 Jaguar at the Oak Ridge National Laboratory (ORNL) in Tennessee that can carry out only 1.75 petaflops per second. One petaflop is the equivalent of 1,000 trillion calculations per second.
The news about the machine broke just before the publication of the biennial Top 500 Supercomputer list which ranks the world's most powerful machines.
Prof Jack Dongarra from the University of Tennessee, one of the computer scientists who helps to compile the list, said China's claim was legitimate.
"This is all true," he told BBC News. "I was in China last week and talked with the designers, saw the system, and verified the results."
He added: "I would say it's 47% faster than the Oak Ridge National Laboratory's machine, 1.7 Pflops (ORNL system) to 2.5 Pflops (Chinese system)."
Tianhe-1A is unusual in that it unites thousands of Intel processors with thousands of graphics cards made by Nvidia.
The chips inside graphics cards are typically made up of small arithmetical units that can carry out simple sums very quickly. By contrast, Intel chips are typically used to carry out more complicated mathematical operations.
The machine houses its processors in more than 100 fridge-sized cabinets and together these weigh more than 155 tonnes.
Based in China's National Center for Supercomputing in the city of Tianjin, the computer has already started to do work for the local weather service and the National Offshore Oil Corporation.
Looking for new ways to grow your online business? This issue we have some helpful resources to help you do just that, including five tips to improve your website's design, a checklist for superior customer service and insights from a leading consumer electronics retailer.
When it comes to website design, even seemingly small design elements can affect your sales—one way or another. Here are five design "do's" that can have a positive impact.
Make sure your shopping cart link is easy to find on a page. Use contrasting and/or bold colours to call attention to CTAs, which allow them to stand apart from other elements and get noticed.
People respond differently to different colours. Cool colours like blue and green have a calming effect. Warm colours like red and orange inspire passion and impulsive actions. Using red (or other warm colours) for your "add to cart" buttons will help increase clicks on those buttons.
For clarity, place descriptions and buttons near the products they're associated with. Make sure each product, description, and button group is separated from other groups to avoid confusion.
Show your product image, then your product description, and then your "buy now" button. Organize design elements to follow the buying process that goes through the customer's mind.
Allow your design to breathe. Whitespace helps elements on a page get noticed, communicating the desired action to users. Whitespace also improves usability, is aesthetically pleasing, and increases comprehension.
A few simple changes can go a long way towards helping increase sales on your site. Experiment with the above do's and turn more of your visitors into customers.

PC World

If you use Linux on your company's desktop or server computers, you're already familiar with many of the security advantages the open source operating system offers over its Windows and Mac rivals. What many people don't realize, however, is that Linux can also be used to rescue a computer that has been crippled by malware.
Malware is a frequent occurrence in the Windows world, in particular, and it can be devastating. When a Windows virus strikes, not only can it become difficult or even impossible to continue using the affected machine, but it can be dangerous as well, since prolonged use can further the infection.
That's where Linux can be a life-saver. Without ever having to install the free alternative, you can still use it temporarily on a PC to get rid of any infection. Here's how.
LiveCDs and USBs are a wonderful thing in the Linux world because they let you boot a machine directly from the CD or USB stick without ever having to access the computer's boot records. Not only are they a great way to take Linux for a test-drive, but they can also be put to work when Windows can't.
By far the fastest way to get a LiveCD or USB is to download the .iso file of the Linux distribution you'd like to use and then burn it onto a CD or USB stick. Since Ubuntu is the most popular distribution out there, I'll go with Maverick Meerkat--the latest version of the software--for this example.
Ubuntu can be downloaded from the project's Website for use on a LiveCD or USB; download links for other distributions can be found listed onFrozenTech. UNetbootin is another nice option if you want to go the USB route, which tends to run much faster.
Of course, to take either of these options you'll have to have a working, Internet-connected computer. If you don't, or if your Internet connection is slow, you may want to order a LiveCD or USB via snail mail. OSDisc and LinuxCD both offer a variety of options; pricing is about $2.
Once you're equipped with a Linux LiveCD or USB, you'll need to make sure the infected computer is turned off, and then turn it on again with the CD or USB installed. This will boot the computer into Linux, completely bypassing Windows and its infection. Again, nothing has been installed -- you're simply using Linux to get the machine running reliably again.
Next it's time to get the Linux-based ammunition you'll need to wipe out the malware: antivirus software. I'm going to use ClamAV, my favorite, via ClamTK, which provides a nice graphical front end.
From the main Ubuntu desktop, then, go to "Applications" and then "Ubuntu Software Center." Choose "Edit" and then "Software Sources." You'll be presented with a box entitled, "Downloadable from the Internet," and you should be sure all four boxes are checked before you click on "Close."
Next, from the main Ubuntu Software Center page, click on the "Accessories" icon and type ClamTK into the search box. It will be shown as "Virus Scanner," but if you click on "More Info" you can verify it's the right package. Click "Install" and wait for it to download.
Once installation is finished, you should launch ClamTK by going to "Applications" in Ubuntu's main menu, then "Accessories" and "Virus Scanner," which is how the software will still be shown.
When the ClamTK window opens, click on the "Scan" tab and select the option for a Recursive Scan. Next, you'll need to tell the software which drive you want to check for viruses, which in this case is the one that includes Windows. Scanning may take some time, but once the infection is found you'll get the usual options for what to do with it, including quarantine and removal.
Assuming the infection has now been removed, your computer should be clean once again, making it safe to remove the LiveCD or USB and boot back into Windows as usual. As you enjoy your malware-free machine once again, remember that it's all thanks to Linux. It's also not a bad idea to keep your LiveCD or USB handy so you'll be ready for the next time.

How to Secure a Wi-Fi Connection
Many people think that the firewall built into your router will protect you from Wi-Fi snoops. It won't. It will stop someone from hacking into your network from the Web, but it's not designed to safeguard the Wi-Fi signal itself. So you've got to use encryption.
There are a few standards out there. The best known is called WEP, but it's old and ways to hack it are well known to the black hats. If that's all your router supports, use 128-bit WEP keys. Much better though, is to buy a router that supports the newer WPA or WPA2 protocols. Use a strong password, please.
But neither WEP nor WPA will work if you don't turn them on. By default, security is turned off on most routers.
Suppose you and your laptop or netbook are at an Internet cafe. Since you're using someone else's network, there's no way to know if it's secure. I try not to conduct financial transactions, particularly online banking, when I'm on a public network. Sometimes, though, it's unavoidable.
At the very least, be sure your file sharing options are turned off. And be certain that the hotspot is a legitimate one. When you're done, be sure you log out; and if you're working on a public computer, be absolutely certain that you've closed the browser.

| In preparation for meeting with a hearing aid dispenser to buy hearing aids, there are a few steps you should take to ensure that you get the most out of the visit. Most importantly, you should not only have had a complete hearing test administered but you should also have had your test results explained to you in detail. Make sure you have the results handy so you can bring them to discuss with the hearing aid dispenser. In addition, it may be helpful to make a prioritized list of the concerns that you have and the benefits that you wish to get from your hearing aid. You should also call your insurance provider to find out ahead of time if any part of your purchase or any of your fittings will be covered. Unfortunately, most insurance companies do not offer coverage when you buy hearing aids, but some do, and it is important to ask. Finally, if you feel it is necessary, recruit a friend or family member to come with you to the hearing aid dispenser - someone who has no problem saying no to high-pressure sales tactics, should the situation arise. At the Dispenser's Office When you are at the dispenser's office, if you are still unclear about the meaning of your hearing test results, ask about them first and be sure that you understand the answers completely. Next, bring out your prioritized list and ask the hearing aid dispenser to discuss it with you. You should be able to find out which items on your list you can reasonably expect when you buy your hearing aids, and which may not be possible to achieve with your particular level of hearing loss. Then, the hearing aid dispenser should discuss the sizes of hearing aids that are available to you and which have the most benefit for your situation. If you have limited dexterity - such as from arthritis or complications from diabetes - you may wish to buy hearing aids that have larger, easier-to-use controls. If mobility is not an issue for you, you may instead look to buy hearing aids that are smaller and less visible. Next, find out from the hearing aid dispenser which extras or options are available with the hearing aid models that work best for your needs, and find out how much these cost. Consider which options you will actually use, and which are not worth the extra money. For example, if you are in noisy situations many times during the week - you like to go to restaurants, or you work in a noisy environment - then you may want to buy hearing aids that have a directional microphone. If, on the other hand, you rarely leave your home or you are rarely in loud situations, then you may not need to spend the money on this feature. Pricing At this point in the discussion, ask about the price of the hearing aid that you are considering - and get that price in writing. Do not feel pressured by a sales person who quotes you one price, and then offers you a discount "if you buy the hearing aids right now." Make sure that the price you are quoted will remain the same for an established period of time - you should be able to leave the office of the hearing aid dispenser in order to think about your purchase for a day or two, and you should able to return at a later time when you are ready to buy hearing aids at the quoted price. Warranties When you buy hearing aids, it is also important to find out about any warranties offered. Ask how long the warranty lasts and what it covers. You should also find out how much it costs to extend the warranty beyond its initial coverage period, and whether the warranty covers repairs only, or whether it also covers loss or remakes for fit problems. Ask the hearing aid dispenser to explain the entire warranty to you in detail until you feel comfortable that you understand what is being offered. In addition, you should ask what happens when your warranty expires. What types of fees will the hearing aid dispenser charge you for any repairs when that time period ends? Also find out what type of warranty is given on repairs - ideally you will be given a new six month warranty after any repair is performed. Many manufacturers will charge a flat rate for certain repairs, but may require additional fees if a case needs to be remade or other more complex changes need to be performed. Find out this information before you buy hearing aids. Return Policies and Restocking Fees You should also ask about the return-for-credit policy that the hearing aid dispenser has. Federal law mandates that when you buy hearing aids, you be able to return them within 30 days, for any reason at all, and some dispensers will extend this timeframe to 60 days or longer. However, you also need to find out if a restocking fee will be charged if you do decide to make a return. A 10 percent restocking fee may not sound like much, but if the hearing aid costs you $3,000, you will be charged $300 for your return. Look for a hearing aid dispenser that charges a reasonable fee, or, ideally, no fee at all for returns. Additional Important Questions Digital hearing aids will require fine-tuning of their internal programming, and you may need to return to the hearing aid dispenser several times until the hearing aid sounds best to you. Ask how many of these visits are included when you buy hearing aids from that vendor - often three or four will be included, which is usually sufficient - and how much additional visits will cost. Finally, find out the upgrade policy of the hearing aid dispenser. If a new hearing aid product is introduced within a certain period of time, will the dispenser allow you to purchase that for a reduced fee? Will you be allowed to trade in your current hearing aid for the newer model? Try to find a hearing aid dispenser who offers some sort of upgrade policy when you buy hearing aids. At this point in the conversation, you may think it's time to buy your hearing aids, but, actually, it is not. You may be surprised to hear this, but you should be able to walk out of the office, go home, and think everything you have learned. Do not let anyone pressure you into making a purchase on the spot. Instead, before you buy hearing aids, comparison shop, as you would for any other product. Ask different dispensers what they offer and how their products compare to others. And do not make a purchase from someone with whom you do not feel completely comfortable. If you follow the guidelines discussed above, you will be able to weed out the high-pressure salespeople and the bait-and-switch pricing tricks that some vendors use. Instead, you can be sure that you will find a hearing aid dispenser that you can trust and from whom you can buy hearing aids that will improve your hearing and your quality of life.

He strives to be customer-centric in all aspects of his work. |
手很贱，安装了一堆Android应用，不知道是哪个出了问题，导致打开所有的应用，都提示"应用程序（某某进程）意外停止，请重试"，卸载了很多程序依然无法解决，不得已进入Recovery模式，在wipe data里factory reset，重启后正常，设置和主屏丢失，程序在app2sd中，竟然都不用重装。
Android对于底层的过于开放，导致很多应用可能会十分"危险"，目前的Android应用也是鱼龙混杂，不可以随便安装，有些写的不好的程序甚至会威胁到整个系统的稳定和安全，另外Android系统的稳定性的确也令人担心，比iOS还是有着较大的差距。
什么是3G，3G能用来干什么？3G有哪些标准？这些问题估计很多人都不是特别了解，简单来说，3G就是第三代移动通信技术，我们目前大多数人用的叫2G，是第二代，第一代就是大哥大，寻呼机时代，以下你会找到详细的关于3G的具体知识。 (1.)中国移动： 移动使用的是TD-SCDMA（以下简称TD）制式，品牌名为G3。这个标准是移动和国家工信部声称为民族自主的3G标准，所以国家大力推广。但从移动本身来说，它并不想经营TD这个3G标准，因为TD有太多的缺点。 TD实际上并不是真正的民族自主，而是原来西门子的技术，中国的大唐电信有所参与，但所占专利极少，不到TD整个专利的10%。欧洲当年有WCDMA、TD-SCDMA两套3G标准，在最终的结果上，欧洲决定抛弃TD-SCDMA，只发展WCDMA一套3G标准，因为欧洲在做任何事上，都讲究统一原则，不可能左右手互搏，推出两套3G标准。于是TD被大唐电信捡了回来，稍加改造便冠以民族自主的帽子，成了名副其实的"洋垃圾". 下面是TD-SCDMA的专利比重分布： (2.)中国电信： 电信拿到的是美国高通公司主导的CDMA2000的3G制式，这是因为联通在与网通合并时，将CDMA（也就是原来的联通新时空）网络出售给了电信，也就是原来的联通C网用户现在都是电信的用户了。这个CDMA2000的网络的缺点是大多数专利都掌握在美国高通公司一家，发展缓慢，迄今为止CDMA2000才有Ra和Rb两个版本，而且Rb商用的并不广，因此CDMA2000的上网速度不是很快。另外的缺点是CDMA2000依赖于美国的GPS卫星对其基站精确授时，一旦美国的GPS卫星故障超过72小时，整个电信的网络就会全部瘫痪。其实移动的TD目前也存在这个问题，TD翻译成中文就是"时分"，也就是TD网络依赖于时间区分网络的上下行通信，这就要求移动的TD基站必须在时间上精确同步，因此TD也依赖于GPS的精确授时。 (3.)中国联通： 联通采用的是欧洲的3G制式WCDMA，目前全球80%的国家和地区都在使用这个标准的3G网络，也就是说WCDMA是事实上的3G国际通用标准，只有这种3G制式才可以在3G时代全球漫游。这自然也给WCDMA带来了TD、CDMA2000所无可比拟的优势。WCDMA的技术成熟度高、厂家支持多、全球漫游。 现在我们来对比一下三家的3G： (1.)手机终端： 我们中国的老百姓在运营商、手机、服务等的选择上，其实更看重手机。由于三家的3G网络在手机上不可以互通，也就是说，你要用哪一家的3G网络，就必须买哪一种制式的3G手机，你的3G手机是不能再使用其他两家的3G网络的。 (2.)网络速度： 3G其实没什么神奇之处，不要认为它与现在的2G网络有着什么不同，其实唯一不同的就是3G的上网速度要比2G快N倍，因为网路速度快了，就能干很多事，譬如：视频通话、在线电视、电影下载等等，因此，3G时代的手机应用非常多。那么不管是什么制式的3G网络，你的速度越快，优势自然就越大。 (3.)网络覆盖： 网络覆盖越大，用户体验就越好。目前来说，这一点上，电信的3G网络完胜，这主要是因为CDMA2000可以直接从软件升级，而不需要大规模新建基站。 (4.)关于带宽支持： 3G运营商要提供高速上网支持，有一点是必须的，那就是这个运营商要有充足的带宽资源，3G运营商的带宽会由基站接入到有线带宽网络中，也就是相当于ADSL使用的网络。这一点上，联通、电信占据了优势。电信自不用说，人家原来就是带宽上的强者，联通为什么也强呢啊？因为联通在08年中国电信业重组时合并了原来的网通公司，网通可是和电信一样，带宽上的霸主啊！所以联通、电信在3G带宽资源上都是十分丰富的，可以利用其手里的固网宽带。但是移动TD呢啊？电信业重组时，移动合并了铁通公司，铁通的带宽如何，很多人心里都清楚吧？所以你会发现TD访问很多资源都比较慢，这是因为大多数网站都把服务器放在联通（原网通）、电信的机房，移动（原铁通）去访问，当然慢了啊！这个是不同运营商之间的带宽瓶颈问题。你见过有些网站为了提高各地的访问速度，提供联通（原网通）、电信双线接入，可是你见过有提供联通、电信、铁通三线接入的吗？没有吧？所以移动TD在这一点上也决定了它快不了！ (5.)关于网络互通： 由于联通的WCDMA、移动的TD师出同门，二者在技术参数上很多地方都相同（实际上不如说是TD一直被WCDMA牵着鼻子走）。因此TD和WCDMA进行视频电话是非常容易的，也就是说移动、联通可以进行视频电话互打，只不过双方现在还没有实现这一功能，但实际上实现起来并不困难，只不过双方不开放罢了。但对于电信，就很尴尬了，电信的CDMA制式特立独行，在技术上很难做到与移动、联通的3G手机进行视频通话，而且现在很可笑的是电信自己的3G手机都没有视频通话功能，据传说CDMA2000实现视频通话功能在技术上有些麻烦。这点上电信真是可笑之极！ |
相比诺基亚S60第三版手机平台来说，开源的谷歌Android手机软件应用的使用体验要明显高的多，Google Android智能手机平台自从发布后空前成功，获得了如HTC、摩托罗拉、三星、索爱等知名手机商的支持，同时也吸引了越来越多的用户和开发者加入其阵营，其流行和普及的程度已经逼近苹果的iPhone手机平台。
Android平台上的应用非常多，其谷歌应用商店里可以找到各类应用，安装、升级和卸载都非常方便，最另其他平台羡慕的可能是Android应用程序可以直接复制文件到SD卡后安装使用，这为手机应用的备份和恢复提供了非常简单易行的操作模式。下面我就总结的一些最为常用Android手机应用程序列表，欢迎大家补充。
系统工具
来电通
显示来电号码归属地、号码类型，电话短信过滤功能，过滤不希望接听/接收的电话或短信，自动IP电话拨号，自动判断长途电话，自动加拨相应的IP前缀等等功能，该应用在S60平台上也有。
RootExplorer
相当于电脑上的资源管理器，但需要将手机刷机Root后才好使用，具有Root权限后，使用这个工具可以随意操作手机内以及SD卡上的文件，还可以修改文件的权限。喜欢折腾的用户必备。
ES文件浏览器
ES文件浏览器的功能和RootExplorer类似，但不需要Root权限，支持本地文件管理、方便用户对手机和SD卡上的文件/文件夹进行各种操作，新装手机用户可以使用这个工具来安装、卸载、备份应用程序。
ES任务管理器
ES任务管理器是一个手机上的任务管理器，这款软件能够释放内存，卸载应用，清除缓存，节约电量，加速手机。支持桌面Widget，可实现一键释放内存。
优化大师
优化大师提供了手机体检、开机加速、批量卸载、文件管理及数个附加的工具软件。能够有效地帮助用户了解自己的手机软硬件信息；提升手机开机速度；扫描有危险的软件。
Terminal Emulator
手机上的超级终端软件，Android是基于Linux内核的，对于喜欢研究底层的朋友来说，自然不会放过搞明白Linux层面上一些东西的机会。使用Terminal Emulator来启动模拟器并进入shell界面，就可以运行Linux命令，如果手机已经刷机Root了，那还可以使用su进入系统管理员权限。此应用高手必备。
缓存助手
缓存助手在Root权限下可以清除用户系统的缓存，增加使用空间。
百度输入法
Android上的拼音输入法非常多，这点iPhone可比不了，常用的输入法有：百度、谷歌、搜狗、QQ、触宝、91等多种中文拼音输入法，个人感觉百度手机输入法要好用一点。
条码扫描器
BarcodeScanner可用于扫描条码，对于提供网址条码的应用，只需要一扫就自动识别并打开相应的处理程序，可以直接跳转到电子市场进行安装，非常方便。
LauncherPro
Android桌面增强软件，可显示华丽的用户界面，占用系统资源也较少。
HiAPN
海卓HiAPN是一个APN开关应用，提供了在桌面快捷切换通信网络和关闭开启GPRS的功能。Android手机最糟糕的一个设置就是GPRS一经开启就一直连线，并很快耗光手机的电池，因此人们不得不使用所谓的APN开关应用，上网前打开APN，下网后断开APN，整个上网过程比S60和iPhone都糟糕很多。HiAPN可以在桌面上生成一个APN开关，这样打开关闭APN相对来说简单多了。
娱乐应用
天天动听
天天动听是一款集播放、音效、搜索、下载等众多功能于一身，完全免费的手机音乐播放器，支持多种手机平台，操作简易，具有自动下载歌词和专辑图片的功能，是Android平台上最佳的手机音乐播放器之一。
RockPlayer
强悍的视频播放器软件，它几乎支持市面上所有的媒体格式，可播放高清RMVB视频，是Android平台上性能最高、支持格式最广泛的视频播放程序之一。
FBReader
FBReader是Android上开源的EPUB电子书阅读器，使用过iPad和iPhone的同学一定会存有大量EPUB格式的书籍，将其复制到SD卡上，使用FBReader即可进行EPUB阅读。
百阅
百阅是集阅读与社区为一体的手机看书软件，支持多个手机平台，可离线阅读手机内的BRM、UMD和TXT电子书，也可在线阅读网络电子书。
开卷有益
开卷有益是一款掌上阅读利器，阅读多格式文字作品、内置智能排版引擎、智能搜索程式。支持TXT、CHM、UMD、HTML等格式的电子书。
网络应用
谷歌地图
手机版谷歌地图软件，目前手机上公认的最佳地图应用，支持语音导航提醒，支持街景模式，还具有实验室功能，与其他手机平台的谷歌地图相比，Android平台上的谷歌地图功能最多最完善，并且对于中国地图来说没有地理位置偏移。
UC浏览器
UC浏览器是国内使用量最大的手机浏览器之一，支持WEB、WAP页面浏览，速度快而稳定，流量数据压缩率很高，很省流量，对网页进行缩放浏览，优化排版渲染效果，使用户在手机上也能有很好的上网浏览体验。
Opera Mini
Opera Mini有好几个版本，建议使用国际版，该浏览器最大的特色就是支持自动代理服务器，对于中国用户来说，使用Opera Mini后会发现可以从手机上访问Twitter、Youtube等原先无法访问的网站。
Twidroyd
Twidroyd是一个很好用的Twitter客户端，我们都知道，在中国，Twitter官方的Android是无法连接上Twitter的，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。
新浪微博
新浪微博薄的Android客户端，可以从Android手机上看新浪微薄的信息，界面不错，使用体验远远优于S60手机上的同名程序。
腾讯微博
腾讯微博的Android客户端，除了配色外，其他功能和新浪微博基本一样。
Foursquare
虽然网页版的Foursquare依然无法从国内访问，但是移动版本的Foursquare已经恢复了，经过实际测试，下载安装最新iPhone和Android版本的Foursquare后，不需要翻墙直接就能访问，原先需要寻找API才能访问，而现在直接即可访问，据猜测，估计是手机上的Foursquare使用了HTTPS加密通道，所以就能访问。
街旁
街旁是一个类似Foursquare的国产LBS应用，由于其所谓的客户端应用采用的是内嵌网页的形式，因此速度和定位感觉比较慢，经常需要刷新才能出数据。
网易八方
网易推出一款基于LBS地理位置服务的移动社交平台"网易八方"，开启了门户网站推LBS的先河。这是网易看好LBS应用，进军移动互联网的一步棋。这个服务和Foursquare非常类似，用户尝试在新地点"签到"，还可以获得"勋章"，同时，系统支持同步到网易微博、新浪微博、人人网、开心网、豆瓣等平台。
飞信
中国移动的飞信应用可以通过WiFi免费发短消息给自己的好友，对于短信控一族非常有用。
腾讯QQ
腾讯QQ的官方Android手机客户端，体积非常庞大，但功能看上去似乎并不太多。
SugarSync
鉴于手机版的Dropbox无法从国内访问，因此只好用SugarSync这个同样支持Android手机的类Dropbox云存储应用，用户可以通过手机访问到自己远端电脑上的同步文件，还可以将手机上的文件上传到云服务器端，很好用，就是感觉传输速度好像没Dropbox快，期待着Dropbox早日解封。
优酷
优酷的Android手机版，既然不让中国用户访问YouTube，那就只好访问YouKu了。
奇艺
百度奇艺Android手机版提供了大量正版的免费高清电影、电视剧观看，速度不错。
掌上百度
掌上百度是百度为Android手机用户做的客户端软件，除了具有百度搜索功能外，还整合了百度贴吧、知道、新闻等社区平台，界面较为简洁、清晰。
NewsRob
