I just finished doing this and setting up my 4S. Things look more or less ok--but I was surprised to find that I now have two cell phones with the same phone number?!? I can make outgoing calls with either, outgoing texts with either, both show up as the same caller ID--but incoming calls are still going to my old AT&T 3G.
When I ported my number to AT&T from Verizon way back when, the number ported within minutes, and my previous Verizon Windows Mobile phone was just dead. I assumed that porting the same number back to Verizon would go more or less the same way, and that my AT&T 3G iPhone would be dead. This hasn't happened yet. Do I need to do anything to make this happen, or should I expect the porting to be completed automagically at some point in the next day or so?
