The last few times I've connected my iPhone 4 to my Windows 7 64 bit machine in iTunes, it shows up under Devices on the left hand side. However, when I click to see the contents and sync - it shows nothing. It's either a blank white screen or it just says iPhone. I've tried reinstalling iTunes and it doesn't work. This is also with the newest version that was released today. All I can do is either eject the iPhone or rename it. Anyone else having similar issues? Any ideas?
