iTunes freezes when iPhone plugged in

So I've uninstalled and reinstalled iTunes twice, reset the iPhone settings and whenever I plug the phone in, iTunes freezes. The phone charges and appears in iPhoto, but no dice with iTunes. My iPod shows up fine. I haven't installed anything new on the computer (haven't installed much of anything beyond Microsoft Office) and I have a Mac, so I don't think it's a USB driver issue (or if it is, I can't solve it based on other Windows discussions on this topic). Anyone have ideas? I guess I could go back to iTunes 8.2 as someone mentioned this helped, but would really like to get it solves...
