This post pertains to the applications downloaded from the Apple App Store.
Applications downloaded from 'Cydia' or 'Installer', see posting here.
Symptom: An iPhone / iTouch application appears to crash back to the spring/summerboard upon running.
Possible cause: The application was bought under, or synced to, another iTunes or App Store (.Mac) ID.
Possible solution 1: Uninstall, then reinstall the application.
(Programs purchased can be downloaded again free if using the same ID under which it was bought originally.)
Possible solution 2: Re-sync to the original computer profile/iTunes (apps not purchased under the original iTunes/App Store ID will be lost; the app can be re-downloaded [for free] only under the properly purchased ID).
