I'm using Ad Hoc distribution to send preview/beta version of my iPhone apps to customers for approval. I'm always sending a zipped application and mobileprovision files.
Sometimes however I encountered situation when nothing in the application changed but we needed to add a new device for testing.
I've added a device in Provisioning portal and assigned it to a provisioning profile my application uses for ad hoc distribution. I've downloaded new mobileprovision file and imported it to xcode now the question is do I need to rebuild the application to enable the app on a new device or would it be enough to just send old build with updated mobileprovision file?
