Iphone 2g (US version)- not working after updating to latest firmware (3.1.3). It was on version 1.1.4 and hasnt been updated for years. Recently youtube wouldnt work on the Iphone just few days ago (stated must connect to Itunes). So i connected to Itunes and try to update to the latest firmware. After downloaded finished...all i could do is make emergency calls and symbol showing Itunes and a usb. Any advice or making it work again? (phone may have been jailbroken or unlocked before -which a friend did for me-long time ago).
