I posted here about issues I was having with my iPhone. So yesterday evening I had an appointment with a "Genius" who swapped the phone for another. I went home and synced the new phone. My music and photos went onto the new phone, but the applications would not sync (and yes, syncing applications was checked in iTunes and I was able to see my applications there). So I spent an hour or so re-downloading apps. Each one said I'd already downloaded, and asked if I wanted to download again. I said yes, and they're all there. But when I click on them, I get a screen flash and then get back to the main screen. The only things that work are the phone part, mail, and safari (sometimes). Looks like I'll have to go to the Apple Store for the 4th time in the one week I've had the phone. Anyone have any ideas??
