Google just updated the Gmail iOS app, adding improvements that might encourage people to, you know, actually use it. The most important upgrade is support for Notification Center, which means you can now configure the app to show you alerts with message previews.
For everyone who's annoyed by needing to login into Gmail every single time you open it because your session has expired, the updated Gmail now has persistent login. Unfortunately, Gmail for iOS is still basically just a webapp, which means that offline access is still barely there. Little by little, though, it seems Gmail is heading in the right direction.
