Jailbreak iPhone 3.1.2

Since the release of OS 3.1.2 last week, there has been a friendly competition to release a jailbreak for the iPhone 3.1.2. GeoHot was the first to release the iPhone 3.1.2 jailbreak called BlackRa1n, followed by the Dev Team and their PwnageTool.

If I can make a suggestion, do not use BlackRa1n. It is buggy and unstable. PwnageTool is much more stable and “clean”.

This article is a summary of the options you have to jailbreak your iPhone 3.1.2 depending on your model.

There are many reasons to jailbreak your iPhone 3.1.2 (I have 30 of them here) such as being able to install applications not allowed in the App Store, or most importantly, to unlock your iPhone so it works with other carriers.
