Gull1hack: Jailbreak iPhone 3GS with New Bootrom?
Gull1hack is a new iPhone 3.1.3 jailbreak tool developed by a group of hackers that claim to have found an exploit in the iPhone 3.1.3 OS.
Two hackers have already found exploits in the iPhone 3.1.3 firmware to unlock the latest baseband 05.12.01 on iphone 3G and 3GS.
This tool will be compatible with all all iPhone and iPod Touch models.
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.
The developer has not mentioned yet when this tool will be available for everyone to download. For now, you can only watch the demo video Gull1hack has posted.
