My brother messed up the iPhone 3 and it can only do emergency calls. No apps, musics, videos, photos, nothing. Just emergency calls. My brother claims that he wanted to update some stuff, but he really means that he wanted to move the ringtones (musics, photos, apps, etc.) from his iPod to his iPhone. But he used the computer to do it, and sort of messed it up. Do you guys know how to change it back to its original form - the iPhone 3 - or a least reset it?
Added (1). Edit: My brother did in fact update the phone with the sim card. The sim card won't work. And I don't know where I could restore the phone.
Added (2). Edit 2: All right, I found how to restore it, but the thing is, something's wrong with the sim card. Anybody knows how to help?
