I'm a new iphone user. I installed many apps from AppStore n everything were fine until this afternoon. After playing Ferrari, all installed apps cannot b run! I restart it but no success. So I install a new pgm, everything worked again. I was glad until I sync it with iTunes for pic n music, it came back. Any permenant for this? Help!!!!!!!!!!

thanks davidgary73. seems tht this is a common problem for iPhones, any permenant fix for this?

I searched over the web, this is happening to iPod Touch and iPhone after iTunes 7.7.1 is launched. Some what, a file call DRM is corrupted in the fone, where all iTunes installed pgm will crash upon loading.

DRM is a file related to iTunes licensing.

Apple is aware of this and they promised the fixes since last year but till today, it is still happening. Hope the OS3.0 will help.

Do not be overly worry as there's a quick solution for this. Simply download a small app from iTunes and install it, the damaged DRM file will be replaced and after that, ALL other iTunes apps will run again.

But then, it will re-occur again, no guarantee, especually u sync it with iTunes. Hope this info helps. Anyhow, I am loving the iPhon very much.

Lucky u dude, it is a known problem but not every single unit crashes. Maybe under certain memory pattern only it crashes.

sorry to hear about yr problem f.stop, for yr application failed to launch (goes back to Home Screen), try the below solution. It's a known issue:

Tips for you bro to avoid crashing:

1) Avoid syncing with iTunes when you can't install new pgm to solve yr problem when yr overseas.

2) On running any applications, do not press the HOME button suddenly. Go back to the Menu of the application before pressing HOME button.

Been practicing this...
