I've sent my iphone application to my testers and all but one complain that the get error OxE8003FFE when they sync their devices. They are not able to install and run the application. I'm using an ad hoc distribution provisioning profile and all of the testers devices are included in the profile. I'm not sure how to proceed and would really appreciate any help you might be to give.
One more interesting bit of information: The program is a universal iPad/iPhone application. My testers are able to install it on their iPads but not their iPhones.
