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

I cant open apps that were downloaded from App Store. The situation is when the app i double clicked is launching .. then it will close automatically by itself. Want to know under what circumstances case like this will occur. tq

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.
