I got the same problem and i need a help.
When i build .IPA with production profile(not HOC), i download it and try to intall to my device. When i synch the app, the process starts but not ends. It keeps "adding" status.
When i build .IPA with HOC profile, i do the same end it work good, BUT, game center not work
I notice, that in production profile there is no "device"
(in HOC i got 1 device) - my iphone.
AND, i can't add device to production profile, there are no place for it.
