How to Jailbreak an iPod Touch or iPhone firmware 3.1.2
Blackra1n is one of the easiest jailbreak programs made. This jailbreak works for iPod Touch 1G, 2G, and the iPhone 1G and 3G. For an iPhone 3GS or an iPod 3G, this will be a tethered jailbreak, meaning that if you want to reboot your device, you will have to reconnect it to your computer and re-jailbreak. For iPhones, it will also update your base band, meaning that if you were using a service provider that wasn't AT&T, it will reset it to use AT&T again. This jailbreak is very easy. Go to blackra1n.com, and download the file (click on the Windows logo for Windows, and Apple logo for Macs.) Make sure your iPod is connected to your computer, and open the file you just downloaded. Click "make it rain", and you're done! This file will automatically go through the process that made jail breaking harder before. Have fun with your jail broken iPod!
