Iphone not detectable for tethering via USB
It shows up in Itunes via USB and wireless tethering still functions. The network just don't detects the Iphone when connected via USB anymore. It has worked before without any issues. Now it fails both on mac and pc. I've tried shutting both systems off. In "network" it just states that the cable isn't connected or that the unit doesn't answer, but the Iphone shows up in Itunes... I've got no idea why.
What does a network restore do? Is it recommendable?
iPhone 4S, iOS 5.1.1, Mac OSX 10.6.8
