Well, after about 3 hours of checking every so often between breaks at work, I finally read the instruction book that came with the phone...
At first, I plugged the phone up to my mac and got everything syncing over, but no activation. I removed the sim and put it back in-no go. Got a message saying it may take a bit... Even called ATT/Apple support and the guy said the servers were getting hung up with so many activations.
Well, read the little book saying to call ATT or go online to activate. I called, punched in my numbers, it said to turn off for 5 minutes then turn back on...I did this and it worked within seconds...
I'm like many of us-ready to get the darn thing going with excitement running through me, but taking time to read the included booklet (it was on the front page) worked like a charm! If you guys haven't done so, try it!
