Hello!
When you left the Apple Stiore, did they tell you that you had to go home and "Activate" your phone?
I had the same situation, battery, but when I was at the Apple store they did everything for me. So in essence, when I left the Apple store, I was making phone calls and everything. When I went home, I just had to sync all of my data, but did NOT have to activate.
Reply???
