I have a iphone 3g Ver. 4.2.1 BB 05.15.04
I just got a T mobile plan yesterday. The problem I am having all of a sudden is I can't make calls? When I try to make a call, all of a sudden my reception dissapears and my signal says "NO SERVICE" and it consistantly keeps trying to find service for about 10+ minutes. I made calls perfectly fine yesterday and this afternoon. Just all of a sudden the phone/service started acting up. Let me know how to fix this problem asap please!!

SOrry if I posted in the wrong section, I didn't know if this was suppose to be for T-mobile or Unlocked thread...
