lol didnt work. cydia keeps crashing and no apps open. maybe bad jailbreak, maybe its the firmware. whos knows. im just lazy and gonna stick with 3.0 JB for now lol.. ill just use my 3.1 b SDK to dev. apps on and use the simulator but i wont jailbreak till apple sends the final 3.1 at me. but yea its glitchy so if your in the dev program like me and got your hands on 3.1 b go ahead and try to JB but it didnt work for me. let me know how it works out for you. BTW this is on an iPod Touch 2G not my iPhone 3GS. that just has plain 3.1 on it. i know its obvious cuz of the "ipod touch 2g" category this thread is in, but just incase you were wondering.
