I was copying pictures and videos from last night's concert from my iphone to my pc (just using a cable and Windows Explorer). Strangely, my phone wasn't "popping up" iTunes on my PC like usual, and when I opened iTunes manually, the phone did not "show up". Then the last file, a 4GB video file, was not showing up to copy out of the phone in Windows Explorer.
I ended up implementing the following process, which fixed both weird behaviors believe it or not.:

Right-click the Apple Mobile Device entry in Device Manager and choose Update Driver Software.
•Select "Browse my computer for driver software."
•Select "Let me pick from a list of device drivers on my computer."
•Click the Have Disk button. Note: If the Have Disk option is not present, choose a device category such as Mobile Phone or Storage Device if listed, and then click next. The Have Disk button should then appear.
•Click the Browse button and navigate to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers.
•Double-click the "usbaapl" file. (This file will be called "usbaapl64" if you have a 64-bit version of Windows. If you don't see "usbaapl64" here, or if there is no Drivers folder, look in C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers. instead).
•Click Open in the Have Disk window. Then, click Next and then Click Finish. Windows will install the driver.
