The jailbreaking saga continues. As soon as Apple released OS 3.1.3 for the iPhone, the legendary Dev Team got to work. However this time don't throw caution to wind and jailbreak your device at your own discretion. As of now only the iPhone 2G, iPhone 3G, and the iPod Touch 1G can be jailbroken, which means 3GS owners have to play the waiting game which putting it eloquently, just blows! So if you don't own the iPhone 3GS and itching to jailbreak your updated device just follow the instructions below.
The first step involves you downloading the latest 3.1.3 firmware from iTunes and the RedSn0w 0.9 jailbreak like before. When you download RedSn0w 0.9 , then opt for 3.1.2 as the firmware.
Once you launch RedSn0w, it will check if you chose the correct firmware and then will patch the file.
If you have never jailbroken your device and want detailed instructions then you can read our tutorial here.
