I have an older Mac Mini with a PowerPC processor. I just bought an iphone 4 the other day and when I plugged it into the computer, itunes told me that I needed OSX 10.5 Leopard to sync with the iphone (I had OS X 10.4.11 Tiger). Well, I got OS X 10.5.8 Leopard installed today. Now, when I plug my iphone 4 into the computer, iphoto opens and recognizes it, but itunes 9.2 does nothing at all. It's like it doesn't even recognize it. Any ideas?
