iOS 4 GM jailbroken one day within release

The Gold Master of iOS 4 that was just released yesterday after Steve Jobs WWDC keynote has already been jailbroken by msft.guy. This was accomplished by using some hackery along with the Dev Teams's existing Pwnagetool.

The Dev Team has stated that they do have a working jailbreak for the final iOS 4 but we will not see that until June 21st or shortly there after so it may be wise to hold off on this particular hack. But if you are feeling brave and just have to jailbreak your iPhone 3GS running the iOS 4 GM then feel free to give it a try using these directions here.

Video after the break!

iOS 4 GM jailbroken one day within release


I am really hoping the Spirit team gets their JB out really soon. I don't want to have my new phone without a JB. COME ON TEAM SPIRIT!!!

Wow that was quick...somebody call Steve jobs, I'm sure he's not happy lol. I jailbroke my iPhone 3G a while back before I sold it. Now I'm a evo user, more freedom less hassle. Good job hackers, we love you!

The level of motivation should be high among jailbreakers because the best ever potential reason for jailbreaking now exists: blocking iAds.

Anyone know if an unlock is accomplished as well? I'd like to jailbreak/unlock this 3GS before I sell it on the 24th, and unlockability will be calling the shots for me on this phone. I'm still on 3.1.2 myself.

I know these guys always want the glory of being first. But to be honest, I wish these guys would wait till after the release and the OS/Phones are in people's hands.

This does not use any new exploits so a release is not an issue..there are still exploits waiting for the new phone

Unbelievable. Well done. I hope it come out with Spirit. JB both my iPhone and iPad with Spirit.
