In preparation for upgrade to iOS5, I need to back up and sync. I see that my iTunes doesn't show all my apps on the phone, and when I want to sync the apps, I am getting a message that gives me the impression that the phone will be synced to the PC, not the other way round. I want to keep my apps on the phone and want to keep them organized in folders as they are now. What do I need to do to sync it right? As a side question: how do I transfer purchased items (apps) to the iTunes library? I am told I need to do that before upgrading. Thank you!
