With the first beta of iPhone OS 4.0 released just over a week ago, I think the hot topic topic for many has been the question of jailbreak. While there has not been any doubts that it would be jailbroken in the end (MuscleNerd showed off a jailbreak roughly a day after the initial release), I don’t think anyone actually expected a generally available jailbreak any time before the final summer release.
Guess what, there is one already! The Dev-Team have released a BETA version of their redsn0w 0.9.5 tool capable of jailbreaking an iPhone 3G. At the moment the package works on the following:
iPhone 3G only (for now)
Mac OSX only (for now)
the 4.0beta1 FW only (for now)
I have to make a special emphasis: the jailbreak is aimed at iPhone developers only and REQUIRES a properly-registered developer UDID with Apple to get past the activation screen. For the same reasons it does not support Windows, unlock or hacktivation.
What do we, common users, care? Actually – a lot! The generally available jailbreak means developers can start adapting their jailbroken apps for the new OS immediately (rather than waiting for the official summer release) and should considerably shorten the time we will have to wait to get them fully working on our brand new JB OS 4.0 iPhones!
You can find the full Dev-Team explanation after the gap, as well as instructions on what to do in case you upgraded to OS 4.0 beta 01 already and wish to downgrade.
