Plugging an iPhone 5 and iPhone 4S (both 6.1.2) into a MBP (10.7.5) causes both devices to frantically mount and dismount. iTunes version updated today (11.0.2 (26)). It appears to happen when the iPhone 5 is unlocked. Not sure whether this is because of either of the below, or both as did not occur before update. 1) iTunes update affecting their connectivity 2) iPhone 4S took a nasty fall and is now very cracked on the back (fall number 2 this morning) Individually they both appear to work fine and can image capture and itunes sync. Let me know what you think guys.
