GMail App for iOS Now appear again in App Store
The Gmail App for / iPad/ iPod from the Google Team was launched few days back, but was withdrawn immediately due to some serious bugs. If you were eagerly waiting for this app, you can now download it and use it. Just go to app store and search for Gmail.
The Labels View
The app works almost like the mobile / iPad version of Gmail. I have tested this on both Google Account and Google Apps account. The interface looks better than the web version with labels.
If you had installed the Gmail app earlier, you need to logout and delete the app and re-install it. This app is free and would be good for Gmail users.
