I hadn't seen that story, thanks for linking it. Just to clarify, that story is about consumer BlackBerrys which were known to be insecure, where the keys were at the mercy of RIM's willingness to protect them.

I was talking about enterprise BlackBerry systems being unbreakable to governments. That story does not contract this. However, it's saddening to hear that RIM apparently coughed up the keys for consumer BlackBerrys even though it didn't face an existential threat. If they had refused, I doubt that they would have been banned in Canada, being their home turf and a darling of the Canadian industry at the time.
