as far as i can tell, it will be available to all phones on wm6... so yes, the i760 will be able to update. it is 7 that is sketchy in that dept. there will also supposedly be threated sms and other such things. at&t im sure will take to the release right away, but vzw like usual with most likely have to wait a few weeks at least. i just hope it enables EMS.

also, the phone carriers should be able to back up your settings, do the update, and then swap... that is what i was told anyway. so hopefully no headaches there. i guess only time will tell. IF there is an update.
