If you haven't heard, we've got an unreleased copy of Gmail 4.2. Yesterday we showed you the major new features: pinch zoom and swipe to archive/delete, and today we've made a few more discoveries we thought you'd like to know about.
As usual, the old (well, current) version is on the left and the new, unreleased version is on the right.
Attachments have been totally revamped. For starters, attachments are now below your message, where they belong, instead of above, like in the current version.
