"InstallProhibited" received from device

I recently updated my iPhone to iOS 4.0.1 and I cannot use the device for development any more. I have the following error when Xcode installs the app on the device:

"InstallProhibited" received from device.

The provisioning profiles are correctly insta开发者_开发知识库lled and I could use the device for testing before the iOS update.

Did anyone encountered this error? I googled a bit but couldn't find anything related.

Many thanks in advance for your suggestions!

Check the Settings->General->Restrictions setting on your device.
