Answer 2

XCode 4 has a fun little bug, here's how you might fix it:

Check what version of iOS SDK you have selected under your target. Click on the project in the nav tree, then summary. You should see a 'deployment target'. If that's in grey, then it's being auto filled. For some reason, this causes the 'no provisioned device' error.

(Edited: You tagged for XCode 4, so no reason to say 'if you're running...')

By click on project, etc etc, I mean the following:

Use the navigation tree you have to select different files to edit, and scroll to the top of it. At the top should be a blue XCode icon labeled file (that acts as a directory, I know) with the name of the project. Click on that. In the window that opens on the right, you should see a tab bar with a tab labeled 'summary'. Under summary, check the deployment target.

Answer 3

Has your provisioning profile expired? Is the profile you are using able to provision the app you are installing?

Answer 4

You may have already tried this, but I've found that this kind of thing is often solved by unplugging/restarting the device, and quitting/restarting Xcode. If that fails, I'd look at project OS version settings, provisioning profiles on the device (expired?), etc.
