No provisioned iOS devices are available with a compatible iOS version

Question

I'm trying to test my app on an iPhone 3G, however I'm getting this error:

No provisioned iOS devices are available with a compatible iOS version. Connect an iOS device with a recent enough version of iOS to run your application or choose an iOS simulator as the destination.

Note that:

• The 3G has version 4.2.1 of iOS installed
• The iOS deployment target is set to version 4.2
• The device has valid development profiles installed
• I'm using the latest Xcode 4

I'm at a loss. Can anyone help?

Solved this problem by closing and re-opening xcode.

Xcode... it's the new Windows.
