Here's what I got going on. I reinstalled OSX, clean install. I kept my Time Machine backups so I can go back and retrieve anything I want. When I connect my iPhone and iTunes pops up . The phone syncs. When I view the iPhone in iTunes all the applications are gone, can I restore my applications from a previous backup in Time Machine? I have seen the prompt from iTunes that says if you sync, blah blah, you will erase all the applications on your iphone. That really is the big kicker. Do I have to wipe out all the applications on my iPhone and re-download them from my iPhone? Can I restore them?
