well i recently got my 16gig iphone jailbroken (the one with the silver back and the bottom is black) and i was going to unlock it aswell but then when i hooked up my iphone to itunes it said usb not recognized it would do that before and after a few tries it would work but now it doesnt want to pick it up at all and now the charger wont even charge my iphone so my bro for some chose the erase all content option and the iphone froze after it finished it stayed on the apple logo and wont load and i cant recover it because the usb wont pick it up so my question is: Is it the usb cable that is messed up or is the the iphones dock connecter that is messed up????
