As we reported earlier, the developer of the Redsn0w and PwnageTool jailbreak software tool, the iPhone Dev Team, releases a new Unofficial PwnageTool Bundle to aid iPhone 3GS (old bootrom) users to easily update their iPhone 3GS to Apple’s latest iOS 4.2.1 operating system while preserving the baseband of their device in order for them to use the Ultrasn0w 1.2 carrier unlock tool to unlock their iPhone 3GS without the need to update its baseband to 06.15.00, which is required for Ultrasn0w 1.2, however the procedure is bit complicated. Because there is no way to come back down from 06.15.00, and there’s no hiding the baseband version from Apple. Additionally, it will void the device’s warranty form its maker.
The iPhone Dev team said on its official blog:
“For those Mac users with an old-bootrom 3GS who really know what they’re doing, here’s a minimal 3GS 4.2.1 bundle that will get you to 4.2.1 without updating your baseband. Be sure to uncheck “Activate the iPhone” using Expert mode. To actually jailbreak after you’ve restored with the help of that bundle, please use redsn0w.”
The procedure on how to install the PwnageTool bundle for iPhone 3GS with old bootrom can be found here. You will need to download the PwnageTool Unlock edition 4.1.3 as well as the Unofficial PwnageTool bundle from this link.
