> Apple doesn't serve the same encrypted binary to everyone. Each user has an independent set of FairPlay keys and Apple serves up content encrypted for that particular user. That's kind of the whole point of FairPlay. If Apple served the same encrypted blob to everyone, then the encryption would be completely useless as everyone could decrypt it.
I used to think this as well. However, (my memory is fuzzy on this so take it with a grain of salt) a year ago I downloaded the same app from two different iTunes accounts. Both encrypted apps were identical, and had the same encrypted blob. So it seems Apple is not distributing a unique encrypted blob to each user, at least as far as apps are concerned.
