ATTENTION PORTERS ! I fixed the issue, activated in 5 minutes!
17 Hours into this, I have been unable to port my Verizon Phone Number to the iPhone.
I called customer service, you know, the 877.800.3701 number.
Now, let me first say this - if you get hung up on, at&t is aware of this, it's a glitch apparently. I kept calling and got someone within 30 seconds of holding. He said there were 0 people in queue, and they keep getting dropped calls.
Anyways, the solution. If you are porting, CANCEL it over the phone. AT&T will reverse, and you will get an email immediately cancelling the activation.
Reactivate, but do a NEW line of service, do NOT port. At&t states that you can port after the madness dies down. I ran through the ropes, my phone is now activated with a different number, for now. I have my old number forwarded, so calls will route to the iPhone.
Also, I am already receiving calls on the iPhone, it took about 7 minutes total...
GOOD LUCK!
