Last week I upgraded to an iPhone 3GS and I can sync everything that was on my touch except all the apps. When I go into itunes it shows me the apps that are currently in my profile and it shows that my iPhone is connected but when I try and go into the app section and click the box where it says to sync all apps, it just freezes and it won't let me click it. I can't figure out why it letting me sync everything else except my apps. When I download new apps on my iPhone and try to sync them into itunes, it won't let me do that either. Any ideas/suggestions?
