The iPhone Dev-Team has released PwnageTool 4.1 which adds supports for the Apple TV 2G and jailbreaks iOS 4.1
Through a combination of the recently released geohot limera1n exploit comex’s recently released pf exploit, and our original pwnage2 exploit, PwnageTool 4.1 works on these devices at firmware 4.1:
* AppleTV 2G
* iPad (firmware 3.2.2)
* iPod touch 4G
* iPod touch 3G
* iPhone 3GS
* iPhone 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 “Expert” 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.
PwnageTool’s main advantage to ramdisk-based methods (limera1n, greenpois0n, redsn0w) is for unlockers — those that need to keep their current baseband and preserve their ultrasn0w unlock. But in this new age of both bootrom- and userland-based exploits, its an excellent platform for continuing the jailbreak through all future firmwares. More on this later! In the meantime, please enjoy this free software and please provide any usage feedback in our comment section below.
AppleTV 2G users: Welcome to the JB family! Right now, about all you can do is command-line stuff via ssh. You also have afc2 available, so you can use tools like ifunbox to move files around. These are the *very* early days of AppleTV 2G jailbreaking, so it’ll take some time for JB app developers to come up with methods to use your AppleTV 2G from the remote, versus the command line. PS: Your ssh password is “alpine”…please change it when you can :)
DFU button: That “DFU” button in PwnageTool is more than it looks like. It guides you through the DFU process, but then also runs the appropriate exploit to convince your device and iTunes that all is legit. The DFU button in PwnageTool is not just your average DFU.
