Okay everytime i try to mod my iTouch 2G i use the program that has the jailbreaking all built in. But at the beginning when u have to install the 2 programs i install the libUSB and after its done it disables all my USB ports on my computer so i cant use my Mouse, Keyboard, Ipod, etc. So i had to restore my computer multipule times. It pretty much screws me over. So if anyone could help me it would be amazing. PLEASE HELP ME!?!? Thanks for your time.
