Hey guys,
I currently have an iPhone 3G 16GB from an official carrier Optus.
However I want to unlock it to other carriers as well.
I have previously done this with my iPhone 2G using WinPwn with no problems
however when i try unlocking and jailbreaking with winpwn on my iPhone 3G, there is no signal available for the official carrier and other sim cards.
Any help is appreciated =)
