How is imessage so hard to reverse engineer that its easier to send someone a jailbroken iphone to use? Surely the protocol can't even change much since many users are stuck on old versions as its part of the OS.
I seem to recall that registering for iMessage requires sending the ID (or a signature maybe?) of real Apple hardware. So you could reverse the API but unless someone has hardware that they don't plan on using iMessage on it won't help much.
How old are these iPhones cause that's the oddest part of that setup I've heard.
