Why iTunes doesn't "see" iPhone 5?
When I connect my iPhone 5 to iTunes (vers. 11.0.4) via USB on my iMac (3,06 GHz ntel Core 2 Duo), the iPhone does not appear in the left part of the iTunes window (or if it it does, it's just a flashing image which immediately disappear), meanwhile the iPhone emits repeated, desperate "beeps". So if I need to udpate the phone software I have to use a wifi connection and not iTunes (to say nothing of putting some of my music on the iPhone). Can anyone help? Thanx in advance
