Answer 1

Try following these instructions:

1. Go to Settings
2. Go to General
3. Go to Restrictions(4-digit passcode may be needed)
4. Turn on "Installing Apps"
5. Resync your Device.

Answer 2

This is not great but it is a solution. I restore my iphone to 4.2.1 iOS (from 4.2.1 !!! strange...) and works great. So my only conclusion is that is NOT Xcode problem but device/OS problem.
