I spent awhile on the phone with At&T today...they said everything looked fine on their end, and said I should be able to receive text messages from anyone. I still have not gotten any! I even went so far as to reset/restore the phone, hoping that would help, but still no text messages. I will wait a few more days for the network to "catch up" but after that, this baby is going back to the store!
