Does this mean someone actually RE'd the entire iMessage cryptographic protocol. I know of several people who have wanted to analyze it.
If so, if they or someone could put up the source or even a protocol spec, that would be amazing.

I posted the APKTool output on Github for anyone that wants a quick look - https://github.com/mdp/iMessageChatDecompile
Put it this way, just like AirPlay and AirDrop, it keeps the open-source community on the backfoot, always looking to "keep up with the Joneses" when in fact we should let these proprietary protocols wither and die.
The public perception shouldn't be that Apple lead and others follow, it should be that Apple have deliberately isolated themselves from everybody else.
* By backdoor, I mean the protocol isn't actually end to end secure in the way Apple claims(i.e. safe from NSLs) and Apple does actually have access to messages. Not that the protocol looks secure and they picked backdoored primitives or some secrete key escrow scheme, though they may have done the latee at least in other cases[0]
