When I connect my iPhone 3GS to my computer, iTunes does not detect it. The phone displays the green battery meter indicating it's charging, System Profiler detects an "iPhone" connected to the USB bus, and I can even open iPhoto and pull some pictures off of it.
It doesn't appear under "Devices" in iTunes at all, nor does it appear in the Organizer window in Xcode.

(I'm on OS X 10.6.6 and iTunes 10.1.2)
