I expect Apple will silently rollout a fix in 5.1 or later seeing as they haven't made a public statement on it. Change log will probably just read 'iMessage enhancements'
Seems to be just a feature of multi device messaging.
So anyone who has their phone stolen has to de-register the stolen SIM otherwise that thief gets your messages even after you get a new replacement.
Not a mystery I guess, just seldom mentioned and no fix needed apart from user awareness.
True. With it being Apple though, I'd expect them to want something similar to how you can deactivate all PCs associated with your iTunes account with a couple of clicks; taking away any confusion for the end user. Then again, there maybe some technicalities that prevent such a 'simple' method from being implemented.

They don't need to "de-register" the SIM, they need to "de-register" the device from iMessage - something which is currently impossible without actually having the device in your possession.
According to the Loop, if the employee had toggled iMessage on and off in the iPhone's Settings after putting his SIM card in the phone, none of this would have happened. Apple says it's not a bug, effectively, but it seems to us any situation where someone's messages wind up on somebody else's phone is definitely a bug, even if it only occurs in rare situations.
Update: I've been able to recreate the bug that we reported on yesterday. After placing my iPhone 4S SIM in my wiped iPhone 3GS, the 3GS turned on iMessage and began receiving and sending iMessages. It did this without prompting me for an password. After pulling the SIM out of the 3GS, the phone continued to receive and send iMessages. I followed Apple's advice and toggled iMessage on and off and that removed the account.

That's agreed. But prehistoric seems to have an advantage at the moment with many people still using BBM. On the one hand, I am surprised Apple didn't say iMessage would be an open protocol like they said Facetime would be (even though they still haven't opened it up).
