Couldn't activate and now can't restore
I was trying to give my old 3G to a friend who is on T-Mobile, and after using Pwnage 4.1.2 I had the phone up and running but when we put the SIM card in, it never found the T-Mobile towers. Why didn't it activate?
The first time through I did not use the Expert mode, so I suspected that was the problem and tried it again with that mode, but that failed. Then in a panic I tried to restore the phone with iTunes which downloaded the latest iOS update. However, it fails with an error.
So at this point, is there any hope for me getting it to work again with either iTunes or Pwnage?
