I have a jailbroken iphone 3g and i wanted to restore it to update to version 3.0 . Suddenly an error shower up saying that my iphone could not restore. So i took my iphone off the usb.as i did so the screen lit up and showed me a picture of a normal usb ( not the one you connect to the iphone but the one you connect into your pc) and an arrow on top of it in the direction of an itunes symbol! When i tried reconnecting the iphone itunes did not open automatically, and does not find an iphone inserted! My PC finds a usb device but even when i try to download the hardware it says no hardware found! PLEASE HELP ME!!!!!
