I've got a question about the whole iPhone Beta 3.0 Activation process. I've got a developer account, and I have a few people who want to beta test my Apps on the new 3.0 OS. I know I can add them to my account and they can install it no problem, but if I remove them, what happens to their device? Would I have to keep them added until the OS is officially released or does it just check when installing.
