Hi, I have an iPhone 3GS, with 5.0.1, firmware 05.16.05 and want to unlock it to use it in Greece (used it in the US before). If I have understood it right I have to jailbreak it first with Redsnow? Can I unlock and jailbreak it with the same program? Can somebody please help me out? I saw a lot of posts, but they seem quite complicated and I have also read and seen on videos that it should be easy, so, what to do? I understand that I have to upgrade my firmware first (does this mean an ipad baseband or what?), or has anything already changed and it is not needed? As information, my computer is quite old (imac mac os 10.4.11). Will I have any problem in running the jailbreaking/unlocking programs on my computer in order to jailbreak/unlock my phone? Thank you very much in advance!!!!
