I was given a near mint iPhone 3G in the box when a friend upgraded to the iPhone 4S. She went to AT&T and they copied over her settings etc to the 4S and now the 3G says 'no service". I put in my AT&T sim card from my old flip phone and turned off data in the phones settings, tested it and it makes calls and receives calls.
My questions is: what is the proper procedure for this. I DO NOT want edge/3g data. I just want an iPod touch (with wifi) that MAKES calls. I don't care about any messaging of any kind. The phone still has my friends stuff on it. Can I restore it in iTunes and put on my apps etc, or will that kill the activation? Should I use unlockit.co.nz and change the carrier settings. Does it need to be jailbroken?
