Google has released a major revision to Gmail for mobile, running in the iPhone and Android web browser. First, you’ll notice that it’s a lot faster when performing actions like opening an email, navigating, or searching. And if the data network drops out on you, rest assured that Gmail won’t. You’ll still be able to open recently read messages and to compose over a flaky, or non-existent, network connection. All this is achieved with aggressive caching and by leveraging new browser technologies, like HTML5 and Gears. Also updated the user interface, made it faster to open messages, allowed for batch actions (like archiving multiple messages at once), and added some basic offline support. The new Gmail for mobile will also help you tackle your inbox faster. Go to gmail.com from your mobile browser to give it a try, and stay tuned for feature additions and improvements.
