Ad hoc doesn't appear in iTunes

I've updated a 3.x app to sdk4. I have iOS4 installed on my phone. I drop the Ad Hoc version of the app into i开发者_如何学PythonTunes. It prompts to replace the provisioning profile and I click yes. Then I don't see the app in iTunes. I do have the iTunesArtwork file in the resources folder. Any ideas what I'm doing wrong?

I'm running Xcode 3.2.3 and latest non beta sdk (4).

This usually happens when in your projects .plist file you have the

Application requires iPhone environment

set as false.

Check the checkbox along the above key (enter it verbatim if it's by some means not present there)

Should fix your problem.
