The framework versions on disk do not match the versions on the device. Delete the folder:

/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1/

The SDK version (bolded above) can be any installed version. Choose the version(s) of your test device(s).

Plug in your device and start Xcode. Open the Organizer (Window > Organizer) and you will be prompted to restore these frameworks. Once this is complete, restart Xcode and Clean All Targets before building the app for the device.

See: UUID mismatch detected with the loaded library

i think you need to go to the developers website and get your certificate once again. this time match your uuid with your phone and the website.
