Good news for iPhone 4 users that Dev-Team is working on a permanent iPhone 4 unlock exploit .Until now the exploit used by iPhone Dev Team to unlock iPhone 4 based on 2.10.04, 3.10.01 and 4.10.01 basebands. If the new permanent iPhone 4 unlock exploit come into reality it would be a great help for iPhone users.
