If you're a fan of all things Google, you'll be happy to hear that Gmail got a new engine for iPhone and Android-powered devices.

Users of the browser-based email client should notice a performance boost. In addition, if you lose your network connection, Gmail will continue to allow you to check all those damn Facebook emails you get. Google uses "aggressive caching" and the awesome power of HTML5 and Gears to allow you to continue your email checking ways with a horrible connection, or even offline.
