I have an ad-hoc provision profile for my iPhone application and I have installed them on several devices. If I need to add a new device, I will need to re-compile the application with the new mobileprovision file so that it can be distributed to the new device. But what about those existing devices? Do I need to re-deploy the re-compiled application to them?

+1  A: 

No, existing devices will be fine. They just use whatever provision information they have; they don't do any sort of remote check to see if anything has changed.

Note however that if you send a new build to an old device, you need to send the new profile as well--you can't send the new app and just have it use the old profile.
