I'm with Rogers here in Canada and hated the fact that AT&T was on the battery cover so I did a little experiment and it worked.
1) Get a Penny
2) Using the Penny slowly scratch off the AT&T Logo and make sure you don't press that hard.
3) Wipe your phone battery cover and now it is debranded and the AT&T Logo is Gone and you're phone is scratch free.
*** Use at your own risk I did it on my Atrix and it's perfect but I take no responsibility and I can't guarantee it won't damage your phone ***
