My iPhone 4S doesn't show in the left column in iTunes. I'm running iTunes 10.6.
Any ideas on how to troubleshoot this?
1 - Restart.
2 - Hard reset (home and power buttons).
3 - If you have it, the XCode device manager sometimes detects devices that iTunes does not.
One of those three should solve the problem entirely, and if not - jailbroken? also any error messages?
