After losing the ability to use my var folder, http://forums.macrumors.com/showthread.php?t=363000 and archieve installing 10.4 onto my iMac, I can longer sync my iPhone to my iMac. iPods work just fine; and I can see the iPhone is seen on the System Profiler but iTunes does not. I have plugged it in on a hub and directly on the computer to no avail. All my backups for the iPhone are no longer in iTunes. Surely there must be a way to force it to sync again to my computer. Any help?
