okay so , i got my first generation iphone back , my friend locked it so he didnt want to unlock it because it was hard for him and he took his money back. and now its locked , so when i connect it to the computer , it makes a sound , not the normal sound your supposed to hear , but just a different sound. itunes does not open up and even if it is open before i plug it in , when i plug it in , it wont work .. and when its plugged in , on the iphone screen, all i see is the iphone usb pointing toward the itunes icon with an arrow above it .. so its no reading the iphone at all , and the iphone is registered under my computer . also , when i go to Ziphone to unlock it , Ziphone cannot find it either ! i tried restore mode , does not work. and sometimes when i just leave it plugged in , it disconnects n then connects again .. PLEASE HELP !!
