[mediocre inc]

im rooted but have no custom roms. i bought rom toolbox and tried to change my wifi icon up top. i created a backup. now the word samsung appears on boot up. then disappears and pops up again. i want to unroot because as soon as the m7 comes out ill buy that. thanks

I'm in the same position after accepting the over the air update (that I have been postponing for months). I'm on verizon.
