Isn't this the classic DRM style problem?
Just wondering about the encryption on the restore image and encryption/signing on the iPhone itself...
Isn't this the classic DRM problem, you're securely storing data that has to be decrypted by the equipment belonging to the party you're trying to stop from reading the data.
Ergo...(and I'm sure the dev. team have considered this) is the key to decrypt the images not stored within iTunes and could be dumped from memory at some point during a restore process? Or if iTunes calls back to Apple to get the key at some point, could it not be captured from a network session with Apple?
If it's PKI then the cert to decrypt must exist somewhere, if its symmetrical encryption then iTunes (or the iPhone) must know the secret. Even if they've updated the way its done in 1.1.1, a 1.0.2 phone (or iTunes 7.4.2) must have the necessary secrets to decrypt in the first place.
This (memory dump) is the way Blu-Ray/HD-DVD got broken, is it ripe for the picking in this case or have I missed something fundamental?
