Can you add devices to an ad-hoc distribution without re-creating the IPA?

ios, iphone

Solution

I use TestFlight.com for test ipa distributions. This feature is available there. Check this link.

If you are developing your own distribution portal, then you need to write scripts for resigning the ipa with new provisioning profile.

Problem

I need to distribute an app to an unspecified number of testers. I don't currently know how many will be wanting access, and therefore don't have their UDID's. From what I've read on the subject, you need to create an IPA that's signed to the devices (or to a provisioning profile that contains the devices) that are permitted to access it, or something like that? My question is can you add devices to an IPA after it has been created? I was intending to create a website for distribution, and add the devices as and when I receive the ID's. I don't want to go and re-create the IPA each time if I can help it.
