Google Demos Offline Gmail on iPhone

Vic Gundotra, VP of engineering at Google has demonstrated an offline version of Gmail for the iPhone 3G.

The app relies on HTML5 standards which allow for a local database and app cache. These standards allow your device to save a copy of your Gmail locally for access while your phone is in Airport mode or out of service. When you go back online the database could sync back with Gmail.
