PwnageTool 4.1 works untethered on these devices at firmware 4.1:
* AppleTV 2G
* iPad (firmware 3.2.2)
* iPod touch 4G
* iPod touch 3G
* iPhone4
* iPhone 3GS
* iPhone 3G
The primary advantage of PwnageTool 4.1 over Greenpois0n & Limera1n is it 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.
Hence you can update to iOS 4.1 using custom firmware created using PwnageTool 4.1 and also unlock it using Ultrasn0w 1.1-1 to use it with carrier of your choice.
PwnageTool 4.1 also supports AppleTV 2G however the jailbreak is restricted to only command line suff 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.
Follow the instructions posted below to jailbreak any of the above mentioned devices running on iOS 4.1 with PwnageTool.
Step 1: Download and install the latest version of iTunes.
Step 2: Now start iTunes and sync your iPhone, iPad or iPod touch with your PC or Mac so that it backs-up all your important data including settings, apps, music, contacts and photos.
