The iPhone Dev Team has announced on their blog the official release of PwnageTool 4.1. They are calling it their 20102010 event to coincide with Apple’s Back to Mac event.
The download is available for Mac only and will allow you to create a custom jailbroken firmware to restore from, allowing unlockers to preserve their basebands.
From their blog:
Weâ€™re pleased to release PwnageTool 4.1 for Mac OS X (free of charge, blog ads, and donation requests â€” as always!). Todayâ€™s big new addition to the jailbreak family is AppleTV 2G, which was first shown jailbroken in its release week!
Through a combination of the recently released geohot limera1n exploit , @comexâ€™s recently released pf kernel exploit, and our original pwnage2 exploit, PwnageTool 4.1 works untethered on these devices at firmware 4.1:
iPad (firmware 3.2.2)
iPod touch 4G
iPod touch 3G
PwnageTool allows you to restore to a custom IPSW file. For instance, you can restore to a pre-jailbroken firmware while simultaneously maintaining your current baseband (and thus your ultrasn0w carrier unlock). You can also add whatever packages you want in the â€œExpertâ€ mode of PwnageTool, if you wish to pre-install Cydia packages. iPhone 3G users get the additional benefit of selecting their own boot and recovery logos, and features like multitasking and battery charge percentage.
As always, use at your own risk. The jailbreak also works for the new Apple TV.
Let us know your success stories!
