Most of the iPhone users are very happy as the Dev team has released the PwnageTool 3.1.4 to jailbreak iPhone with 3.1.2 Firmware. But the problem is that PwnageTool will only work with Mac. Before you are planning to use your iPhone with any SIM card, you have to unlock it and unlocking of iPhone can be done after you had jailbroken it. We have already covered “Procedure to Jailbreak iPhone With 3.1.2 Firmware Using PwnageTool 3.1.4” and “How to Unlock iPhone with 3.1.2 Firmware Using Ultrasn0w“.

But if you are on Windows you can jailbreak iPhone by getting a custom firmware build that is built using the PwnageTool 3.1.4. Once you are done with the jailbreaking of iPhone you can use Ultrasn0w to unlock it. The main thing here is to get a custom firmware from the Internet and then use it to jailbreak iPhone on Windows.

If you are just looking to jailbreak iphone and don’t care about unlocking then you can use Blackra1n to jailbreak iPhone With iPhone OS 3.1.2 on Windows in just 30 seconds.
