Thursday 7/10 - upgraded to the early version of 2.0. Downloaded apps. Apps worked great. Etc. etc. Friday 7/11 - upgraded to the "official" version of 2.0. I left that alone overnight. Saturday 7/12 - Restored to 7/10's sync, and everything synced properly EXCEPT for my apps. I get this pop up screen: "Some of the applications in your iTunes library, including "AIM", were not installed on the iPhone "Timotheezz iPhone" because you are not authorized for them on this computer." What gives?! I downloaded about 16 apps, and I paid $25 for 3 of them. I don't get what's happening. Can someone please help? It would be greatly appreciated!
