This could be related to the problem here, but since this is happening in my iOS build (not Android), and I have cleaned the project and restarted Appcelerator, I don't know why this would occur.
Note - I did not change my dev environment, update appcelerator, or change any certs on my MBA where I'm developing my app. The only thing that I've changed is app code. I thought that I might see bugs or errors, but I'm not trying to debut either, as I'm building and installing via iTunes sync to my ipod Touch w/9.2. The build process and settings have not changed, so I don't even know where to start.
Work around more than an answer, but for some reason, my device, registered at apple was not being recognized by appcelerator (see note in my comment for related issue). After logging into apple dev center, and going back to appcelerator, the issue appeared to go away. I don't know if this is solved, but the workaround got me in business again.
