When to use PwnageTool over GreenPois0n? If your iPhone relies on a carrier unlock, YOU MUST use this version of PwnageTool to create custom 4.2.1 firmware files without the upgraded baseband so that you can unlock your phone on the old baseband using Ultrasn0w 1.2.

Also as we already reported, fix for iBooks and WiFi problem on jailbroken Apple TV 2G will be released soon as a Cydia package.

Instructions for jailbreaking using PwnageTool are similar to the last release, simply follow them as posted here. Select iOS 4.2.1 IPSW file where required.
