The newly released iPhone 3.1.3 firmware for iPhone and iPod touch brings bug fixes and more stability for iPhone 3GS, 3G, 2G and iPod touch users. Since Apple has fixed most of the loopholes which were exploited for jailbreaking and unlocking iPhone 3GS, 3G and newer iPod touch 2G and 3G models are currently unjailbreakable until new tools are released. Fortunately for iPhone 2G and iPod touch 2G(older models only) and 1G users, you can use redsn0w 0.9.3 to jailbreak your device on iPhone 3.1.3 firmware.
[UPDATE: Redsn0w 0.9.4 is now available. Please read the update note below.]
The following guide is strictly for iPod touch 1G and the older iPod touch 2G only. Newer iPod touch 2G and iPod touch 3G users should wait for the new tools before jailbreaking their devices.
Step 1: Update to original iPhone OS 3.1.3 firmware via iTunes. Downloading and installation instructions for iPhone 3.1.3 firmware can be found here.
Step 2: Start redsn0w 0.9.3 and point it to the original iPhone OS 3.1.2 firmware for iPod touch to proceed. This is required because redsn0w 0.9.3 can not read or validate iPhone OS 3.1.3 firmware.
Step 3: Now select both “Install Cydia” option.
Step 4: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
Step 5: Sit back and enjoy while redsn0w will do all the rest for you. Once done, your iPod touch 1G/2G will restart automatically and you will find it jailbroken on firmware version 3.1.3.
