If you were thinking offline Gmail on your desktop was the greatest thing since sliced bread, prepare yourselves people. If an MWC keynote from Google's VP of engineering, Vic Gundotra, is any indication, the same functionality might be coming soon to an iPhone / Android phone near you. Amongst other things, the souped up web app boasts an overhauled interface, supports labels, and of course, offline access. Despite our own hunch that Google's just using black magic and voodoo to make this happen, Gundotra claims that it's all made possible through HTML5 standards -- AppCache being the biggie. This development certainly opens the doors to more offline-enabled web apps in the future -- Docs, anyone?. Of course, we know Apple has a thing about people messing with its own apps, so it's probably going to take some time / knee-breaking to get them to come around, but for some reason, we don't think it'll take as long with Android. There's a demo video available after the break, and please, try to contain yourselves.
