Can someone post the model # of the sim card that came with their iPhone 4S?
From what I am hearing from AT&T reps is that it is a special sim for 4G service, so you can use your old iPhone 4 sim, but you will not get 4G speeds!
My understanding is that this isn't the case. The old micro-SIM will work just fine in the new 4S with the new faster speeds.
