About how many iPhones will the app be installed on? (1-12, 100+)
I ask because if it is only a few (<12), one possible way is to register those iPhones as development/test devices by including them in the certificate. But for a large number of devices, this method would not be practical. Also, the test certificates will expire I think every two years, so you will have to re-register the development when this happens.
