What to do if iTunes Stops Seeing Your iPad or iPhone
Ever since I upgraded to iTunes 9.1.1, I've had the situation where iTunes won't see my iDevice when I plug it in. Apparently, I'm not alone in this.
If this happens to you, the fix I finally found buried deep inside one of the Apple support fora is quite simple: 1. Drag your iTunes application to the Trash.2. Empty Trash
3. Reinstall the latest version of iTunes. Hopefully this will be fixed in a soon-to-be-released update! Since this happens to me almost daily, I keep my iTunes .dmg file handy (no, you don't need to re-download iTunes every time, unless they come up with a new one!) and the whole process takes about 3 minutes. Okay, so that's still 3 minutes too many... Anyway, hope this helps — it certainly worked for me!
Update: I forgot to mention how you avoid the problem happening in the first place:
When you're done syncing your iDevice, and iTunes says "iDevice sync is complete. OK to disconnect.", make sure you click the little "Eject" symbol next to your device in the list on the left before unplugging it!
