After reinstalling Windows 7 (64-bit), it has stopped recognizing my iPhone. I can see it in iTunes but not in Windows Explorer, so I can't get the photos off. I'm having this problem on three different machines and two different iPhones (my wife's and mine). It's maddening.

I've had every version of iPhone since it first came out and I've never had this problem before.

I've uninstalled and reinstalled iTunes (currently at 10.2.1.1). I've updated iOS on the phone (currently at 4.3).

Any ideas? At the end of my rope here...
