Well after much anticiipation I finally got my new iphone 3gs yesterday morning (my first iphone by the way) and I get home and after syncing with itunes I find out that my reception goes from 3 bars to no bars to searching and then no service. And would continue to do this no matter where I went. After switching out a new sim from at&t, and on the phone with apple doing resets and restores nothing would correct the problem. So apple said they would send out a new iphone to me overnight (free with apple care) and I already recieved a tracking number and it shows it will be here on monday morning by 10:30 a.m. Even though I have a useless iphone, the customer service is outstanding. Would not have gotten that if I had to go through at&t. Well guess I wait a couple more days.
