So the rooted Droid users who have FRG22, what changes have you notice between that and the original update?

Can you click the volume rocker down to silent again?

Is the battery life better?

Is gmail update to look like this - Newest Google apps bring welcome changes to Gmail | Android Central ?

I just want to know if anything is changing besides the addition of Flash in the marketplace.
