I have a second generation 8GB iPod touch I got Sunday with OS 3.1.1. It is model A1288 (the newest). I want to jailbreak it so I need to downgrade. I've tried every guide I could find, and no matter what iTunes version I use, if I put it into DFU mode or not, it WILL NOT WORK. I keep getting error 1600. (As seen below in iTunes 8.2 Mac) Please Register or Log in to view images Please, Please, Please help me!!!
