Windows doesn't recognize my iPhone 5
I just got my new iPhone 5 and am trying to restore my contacts from my blackberry. When I plugged in my iPhone there was this notification 'the USB driver not recognized'. I thought it was because iPhone 5 is new so I updated all the system using Windows Update, but still doesn't help. I opened the Device Manager and under I saw that there was a yellow exclamation mark on one of the under Universal Bus Controllers, saying 'unknown device'.
Can somebody help me please?
