Ho to test Apple Push notifications before submitting to Appstore (Urban Airship)

Hi, I'm a little bit lost : I have tested notifications in dev mode with Urban Airship and it works. I would like now to test the production mode before submitting to the Appstore. I use this code (keys changed for privacy)

UrbanAirship.options = {
        APP_STORE_OR_AD_HOC_BUILD : true,
        PRODUCTION_APP_KEY : 'my app prod key',
        PRODUCTION_APP_SECRET : 'my app secret key',
        DEVELOPMENT_APP_KEY : 'my dev app key',
        DEVELOPMENT_APP_SECRET : '-my dev secret key',
        LOGGING_ENABLED : true
    };

I have rebuilt the app and send via adhoc on my iPhone to test. but in error console I get Device token rejected.

What could be the problem ? Is it possible to test it in production mode before submitting to Appstore ?

Regards
