The latest update to PwnageTool from the iPhone Dev-Team is now available to download, and version 4.2 brings with it untethered jailbreaking for devices running iOS 4.2.1 and fixes the recently discovered iBooks issue that prevents a user opening an iBookstore purchase on their jailbroken device.
PwnageTool uses the “feedface” untether developed by the Chronic Dev Team to allow for untethered jailbreaking in the latest release, and supports all 4.2.1 devices other than the iPod touch 2G. Another issue fixed in this version is the Wi-Fi problem that some users had with the second-generation AppleTV.
If you’ve already jailbroken your device and you’re desperate to gain access to your iBookstore purchases, don’t think you need to restore and jailbreak again with the latest version of PwnageTool. On their blog, the iPhone Dev-Team have stated that fixes for both the iBooks issue, and the Wi-Fi issue for AppleTV, will be available in an upcoming Cydia package that you’ll simply be able to download and install on your device.
Once again that’s iOS jailbreakers 1, Apple nil..
