So now that you've downloaded and installed the iPhone OS 3.0 thanks to the Golden Master IPSW being leaked into the torrent world, you're probably thinking it's about time to jailbreak your cool new iPhone 3.0. You probably even did some google searches about jailbreaking the 3.0 and found some highly confusing information (some of it says 3.0 is jailbreakable, other info says it's not.) Well we did some extensive research, and here is what you need to know.
Note: We are talking about the iPhone OS 3.0 Golden Master "7A341". We are not talking about the iPhone 3.0 beta versions (max beta 5) that were released to registered iPhone developers for testing.
information below mostly is not applicable anymore.
The beta versions of the iPhone 3.0 have been leaked as well. These are much buggier than the iPhone OS 3.0 GM (which is literally the same thing as what will be released on June 17th).
The iPhone 3.0 BETA VERSIONS (beta 5) are indeed jailbreakable and unlockable.
There is no official jailbreaking of the iPhone 3.0 7A341 (which is the official version you got via torrent.) You may find information claiming that you can do it by QuickPwn the same way you would jailbreak the iPhone 3.0 beta 5 version, but this is not true. Doing this leads to the "pink screen of death", and you have to restore your phone completely.
iPhone 3G users that have unlocked phones will lose their unlock when updating to iPhone 3.0 because it updates the baseband.
iPhone 2G users can do whatever they want. Nothing will break the unlock for 2G (original iPhone) users because the baseband is not altered. iPhone 2G users can update their phone's to the iPhone OS 3.0 7A341, and jailbreak, and unlock. It works with xxxxxx. Better yet, wait till Friday, June 19th for Dev-Team to release official tools.
If you are an iPhone user that has updated their iPhone to OS 3.0 "7A341" (check Settings>>General>>About>>Version to verify this is what you have) then you must wait for the iPhone Dev Team's official jailbreak. All speculation leads us to believe that it will be available in one week.
