For anyone else whose iPhone 4 is waiting for activation…
“This may take a while.” I saw this documented nowhere but an email from AT&T but you need to activate it not just with iTunes but with AT&T. Ostensibly you can do it at https://www.wireless.att.com/activations/ but it doesn’t seem to work. Just call 1-800-331-0500 first and save yourself the time. The automated phone system had it activated so fast it disconnected my call from my old phone.
Hopefully this saves at least one other person from staring and waiting and googling.
