Update: Gull1Hack Jailbreaking Tool is Fake!
Treat this as a mere speculation. A new group of hackers called gull1b0ard claim to have found an exploit which will jailbreak iPhone 3GS with new bootrom and it will be untethered. The exploit appears to work not only in iPhone 3GS models with new bootrom, but also in all iPhone and iPod touch models. This is where I find the claim a bit fake. The group has come from nowhere, absolute strangers to the jailbreaking world. But if it isn’t, it’s just what so many of us are waiting for!
We just found an amazing Exploit in the Boot-System of the 3GS with the new Bootrom! This Exploit works on ALL iPhone and iPod Touches!
While booting, we overun the buffer memory, letting the iPhone think there is something wrong; But in the moment it tries to enter safe mode, we send a boot signal like Blackra1n or Redsn0w
So no Computer required!
They have released a video clip as a proof for their claim
As someone might noticed, the Gull1hack.app has the option to install Blacksn0w v2. Thats no mistake, it’s our Version of this unlock: There were only a few changes to make it work with the new Commcenter from 3.1.3!
So all people which stay at baseband 05.07.11 will be able to unlock at 3.1.3!
They haven’t given any expected date of release for their tool and as I had warned at the very beginning, this can very well be fake. In the meantime, if you have an older bootrom, you can follow our complete jailbreaking guide for iPhone 3.1.3 firmware for iPhone 2G, 3G, 3GS and iPod touch 1G/2G using redsn0w 0.9.3, redsn0w 0.9.4, sn0wbreeze, PwnageTool 3.1.5. Unlocking can be done using ultrasn0w.
