Hello, I just bought an iPhone on ebay and it came in the mail today. I have t-mobile, so I followed directions to unlock and jailbreak it. I used redsn0w to jailbreak and purplesn0w to unlock since ultrasn0w kept saying "No repository found" in cydia. But when I put in my T-Mobile sim, it says no service on the top and I can't make any calls
, any help is much appreciated.
