The upgrade process was simple, call the 866 phone number, enter your
phone number, zip code and other security info, turn off your new 3G
S, wait 5 minutes, turn it back on and tether it with iTunes to
restore your backup.
- On one of the phones that I upgraded, I had to call AT&T to select a data plan. The phone worked, but the 3G and text messaging services did not.
- On another phone, the text messaging only did not work. I also had to call AT&T.
- On one of the early upgrade phones, the upgrade process went smoothly.
