Got iPhone4 5.1. 04.12.01 firmware... And I want it unlocked.. I can jailbreak it.. But I can't unlock it for my tmobile sim card.. I have a few postings in other areas on the forums.. But no one has contacted me back.. I can also upgrade to 5.1.1 and jailbreak it.. I don't see a unlocking for that either.. If someone AnYONE can help me I can give u my direct e-mail and talk that way if going threw forums is difficult.. Either way doesn't matter to me as long as someone. An help me with unlocking my phone.. If you or someone can help PLEASE do so... Thank you for reading my post..
