I have owned an iPhone for about a month now and I’m very happy with it. Its mail application is acceptable, but it’s not very Gmail-esque. It does not have the conversation view, archiving e-mail means having to move it to “All mail”, which is a bit annoying. Ergo, it works, but it’s not perfect. The Gmail web application on the iPhone is very good, it works just like the desktop Gmail web client and it’s fairly responsive for a web app, it’s only missing one thing: the ability to check for new mails every x minutes.

Over the next few days Google will roll out the Gmail offline feature. Using Google Gears, Gmail will continuously keep a cache of e-mail messages stored locally on your computer so that when you go offline, you still get access to it. The video below shows how it works. As is suggested all of the features in Gmail will continue working while you’re offline, including search. I wonder, does it cache all of your e-mail locally?
