I have a new 3GS phone and when I go to start an App, it starts to load...then shuts right down immediately? I tried restarting the phone but it doesn't fix it. I have about 10 Apps total and they all do this.
I've read about this. I seem to remember it's a DRM failure on one app or so, so just delete one app and then reinstall it. Happened to me once and that fixed it.
Thanks got it fixed.
Had to download all my apps again and re-sync with itunes.
I just got a new replacement iPHone from Apple 2 days ago and finished building a new computer and I didn't have any of my applications saved in iTunes.
