Google continues its commitment with the mobile platform with the release of Gmail for mobile 2.0.
Gmail for Mobile can be used on Blackberry phones as well as all J2ME phones.
The updated app now offers offline support, which allows you to read and compose email messages even when there is no signal. Composed messages are automatically put in the outbox and sent as soon as there is a signal.
There is also multiple account support, which will benefit those with multiple Gmail or Google Apps accounts.
