Gmail for mobile, Version 2.0 for J2ME-supported and BlackBerry phones.
The announcement came both on the Official Google Blog and the Google Mobile Blog a short time ago, introducing Gmail Mobile 2.0.
The primary intention of the new roll-out is to make GMail faster and more reliable.
In addition to speed, the new mobile version of Gmail will include multiple accounts management, multiple drafts, new keyboard shortcuts, and 'basic offline support'.
Here's the video that was posted earlier today by the Gmail team:
