iOS 5 can be jailbroken untethered on all non-A5-based devices. iOS 4.3.3 can be jailbroken easily via a web site but iOS 4.3.4 can't. Confused yet? The state of jailbreaking is a little messy at the moment and it's hard to understand which devices and versions of iOS are eligible. This helpful chart can clear up the confusion.
About This Chart
The chart is pretty large, so click on the image to see the full version.
Green Is Good, Red Is Bad, And Yellow Is Also Kind Of Bad
We decided to make this chart as simple as possible, so it only lets you know if you can or cannot jailbreak your device with a specific version of iOS installed on it. If you can't, the chart will read "No Jailbreak" and the square will be red. If only a tethered jailbreak is available the square will read "Tethered Jailbreak" with yellow colouring. Finally, if a proper untethered jailbreak is available, the square will be green and read "Untethered Jailbreak." (Hint: You want the square to be green.) If your iDevice and iOS version leads you to a green square, check out our guide to jailbreaking for instructions on how to actually jailbreak.
This chart was based on an original by BigBoss. Since that one is a little out-of-date, we decided to make a new one.
