iPhone apps crash on launch (cont.): the fix

We continue to report on an issue under iPhone OS 2.x in which some third-party applications crash or do not launch, for many users. Previous reports indicated that the issue can be eliminated by reducing the number of applications installed on the iPhone. We also noted a separate fix that involves downgrading to an earlier version of iTunes.

We've now discovered a more definitive fix that should, in tandem with reducing the number of applications on the phone, resolve this issue in the majority of cases.

1. On the iPhone, select Settings > General > Erase all Content and Settings.
2. On a Mac, delete the following support files from the computer:
   • /Library/Receipts/AppleMobileDeviceSupport.pkg
   • /Library/Receipts/iTunesAccess.pkg
   • /Library/Receipts/iTunesX.pkg
   • ~/Library/iTunes/Device Support (the entire folder)
   • /System/Library/Extensions/AppleMobileDevice.kext
   • /System/Library/PrivateFrameworks/DeviceLink.framework
   • /System/Library/PrivateFrameworks/MobileDevice.framework
   • ~/Library/iTunes/iPhone Software Updates (all contents)
3. On a Windows XP PC, delete the files in settings/[yourusername]/Application Data/Apple Computer/iTunes/iPhone Software Updates
4. On a Windows Vista PC, delete the files in C:/users/[yourusername]/AppData/Roaming/Apple Computer/iTunes/iPhone Software Updates
5. Delete the iTunes application
6. Restart the computer
7. Install iTunes 7.7 (Windows, Mac)
8. When prompted, set the phone up as a new device and restore.
9. Test some applications.
