For those of you looking to Jailbreak your A4 iOS device running the iOS 5.1.1 firmware Untethered you have a few options. You could use the Absinthe 2.0 Jailbreaking tool, cinject (command line interface version of Absinthe) or a custom IPSW creation tool like Sn0wBreeze v2.9.5. The reason you would want to use Sn0wBreeze over a tool like Absinthe is if you want advanced customization with your Jailbreak, need to preserve your baseband and update to iOS 5.1.1 at the same time, or simply are experiencing errors and think you might have better luck with Sn0wBreeze.
It is important to keep in mind that, as explained before, Sn0wBreeze Jailbreaks your iOS device by creating a custom iOS firmware file that when restored to your iOS device will Jailbreak it. The keyword in that sentence is restored, meaning you are wiping the content off your iOS device in order to apply the Jailbreak.
Another thing you need to realize is that Sn0wBreeze does not support Jailbreaking the iPhone 4S, iPad 2 or the new iPad (A5 devices). The supported devices include the iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G and iPad 1G (A4 devices). As long as you have an A4 iOS device you can indeed Jailbreak untethered on the iOS 5.1.1 firmware with Sn0wBreeze v2.9.5.
Note: Sn0wBreeze is a Windows only Jailbreaking tool.
