As instructed by AT&T I ordered an iPhone from Apple's website using my wife's upgrade on her number. As instructed when the phone arrived before doing anything in iTunes, I called AT&T. I gave the rep two numbers and when she pushed the button my current cell phone died on the spot because the SIM was now unregistered. Now I should be ready to attach to iTunes and and activate the phone but the account in iTunes still shows that it wants to activate with my wife's number. I thought this was possible with no drama? I asked the rep 3 times if she was sure it will work and said they do it all the time. Bummer as I have no way to call AT&T now. Suggestions?
