I haven't downloaded the update, but if we are following the same track as the ATT One X;
This update should give the option to be rid of the black menu bar (Settings -> Display & gestures -> Buttons)?
There might also be some UI changes to the internet browser (tab button relocated to the address bar)?
And the slight possibility of the return of the 'Quick Settings' tab in the notification pull down. Still unclear if that was ever official or maybe will be back with the next update.
Hopefully someone that updates can confirm.
It is labeled MR2 (Maintenance release? so we may not have received all the same One X enhancements yet)
