Got my phone and activated it successfully! I used my wife's upgrade so I simply followed the instructions that came in the box. Turned the phone on, went through the on screen steps, used iTunes to restore from MY last save, then I called the number on the instructions and the rep talked me through the rest. It took about 10 minutes. They even honored my grandfathered unlimited data plan! At first he said "sir, it looks like one option is not going through....the unlimited 4G data plan...." And I said, "I was told that AT&T would allow me to continue my grandfathered unlimited data plan".....he was silent for a few minutes and then came back "OK sir I was allowed to put your grandfathered unlimited data plan in place". AWESOME! Great experience....I love this new phone!!!!
