So i did the steps listed in my title and then brought my old phone to school with me to water polo and checked to see if anyone was on T Mobile so i could make sure the unlock worked. I got out my sim key, took out my old sime, and put his in. Then it said: waiting for activation(this may take some time), and then went to no service. Did I do something wrong? I imagine this is not normal haha... PS: Mine is somehow past the activation screen, It is a refurb I got from apple with my old SIM in it (now on iPhone4). I imagine I just missed/skipped a step here. Edit: This may sound dumb but I did not reboot the phone >.< Is this needed ? Sorry for another thread btw, but this is a completely different issue (I think).
