Silly question I'm sure, but here we go anyway... I'm a AT&T iPhone used since 2007. Last one I had was a 4S, grandfathered unlimited user. Received my 5S today (which was ordered from AT&T), and plugged it into iTunes - used the restore from backup option to get the data onto my phone. All of that was successful, so my 5S is up and running ok. Only thing is, it has not connected to AT&T network yet, I was not asked anything in iTunes also. What should i do to get the data and phone turned over from my 4S to this new 5S ? Thanks.
