iPhone DEV- Team member MuscleNerd has released a video on youtube which shows a preview of the upcoming PwnageTool Jailbreak in action. The new version of the PwnageTool Jailgreak is based on the Limera1n bootrom exploit by Geohot which will allow custom cooked firmwares to be restored without upgrading the basebands on almost all the iOS devices which include iPhone 4, iPhone 3GS (new bootrom), Apple TV, iPad and iPod touch 4G / 3G. This will allow us to unlock iPhone 4 and iPhone 3GS through Ultrasn0w's latest version and use any carrier on the phone as we may like. You can check out the video of the preview below:
The PwnageTool Jailbreak is expected to be available on the upcoming Sunday while iH8sn0w has already confirmed that Sn0wbreeze 2.1 to be released a few days later after the PwnageTool Jailbreak.
