Question

I have an Unlocked Iphone, but for some reason I can't connect to Itunes. It just doesn't detect when i put phone on dock? I tried on many diffrent computer but still. The usb cord, dock is in working condition. Also for some reason the usb charger that came with the phone doesnt work. I tried that charger on a Ipod and it working. I had to get a wall charger that is directly connected from outlet to phone and it works. Anyone who knows how to solve the problems please let me knowThanks Hi, This is a big problem with my iphone and i need urgent helpful answers to fix this problem........
