I made this guide to clear up some of the stuff that lots of people have been asking. DO NOT upgrade to 3.1.3 Firmware on your iPod or iPhone, stay at 3.1.2. If you had the misfortune of updating, here is how you can jailbreak. This will ONLY work on 1st Generation iPod Touches, 2nd Generation iPod Touches, and 1st Generation iPhones and 2nd Generation iPhones. DO NOT try this on any other models, this will not work on ANY devices with the MC serial number, this includes the 3GS, 3G iPod Touch, and newer 2G iPod Touches. Some iPods have a serial starting with a P. This will work with PA and PB serials, NOT PC. If you have a 1st Generation iPod Touch, or iPhone that does not have the MC serial number, you will need to use RedSn0w 0.9.2. If you have the 2nd Generation iPod Touch, you will need RedSn0w 0.9.4. I only tested with 0.9.2, I would recommend downloading both of them and seeing which one works for you. Download Links: 0.9.4: Windows: http://[PIRACY.rs].com/files/345589844/redsn0w-win_0.9.4_4.zip Mac: http://xs1.iphwn.org/rs/redsn0w-mac_0.9.4.zip 0.9.2: http://[PIRACY.rs].com/files/345591618/redsn0w-win_0.9.2.zip Once you have downloaded RedSn0w, you will need to find the 3.1.2 Firmware, yes, the 3.1.2 Firmware for your device. [REDACTED] Once you have found your Firmware, connect your iPod Touch or iPhone to your computer. Now, turn it OFF. Make sure that it is NEWLY RESTORED. Now, you are going to want to start up RedSn0w. Please Register or Log in to view images If you are using RedSn0w 0.9.2, you will have to put your iPod or iPhone into DFU Mode, if you are using RedSn0w 0.9.4, you are going to have to just put it in Recovery Mode. This guide will focus on the RedSn0w 0.9.2, you can follow the on-screen instructions, they are easy to follow. You are going to now select the corresponding Firmware for your device. For this, I used the iPod1,1_3.1.2_7D11_Restore.ipsw file. YOU NEED TO SELECT THE 3.1.2 VERSION, RedSn0w will not detect 3.1.3.

Do not select anything else unless you want a custom boot logo or something along those lines. Please Register or Log in to view images Now hit Next> and your iPod or iPhone will need to be put into DFU mode OR Restore mode. This is easy to do, just follow the on-screen prompts. If your iPhone or iPod turns on, you will need to do the process over again from the beginning.

It took a while to make this guide, just say "Thanks!"
