This is crazy. BlackBerry built a backdoor to its BlackBerry messages service AND shared it with the Canadian police. This is a huge breach of trust from a company that advertised its secure devices, with millions of customers who bought BlackBerries partly due to that reason.
If the Canadian government had it, what makes anyone think that other governments didn't have access to it? They may have obtained it through RIM's (now BlackBerry) cooperation or without through hacking or old-school espionage. Think about it, in the early and mid 90's practically all heads of state including Obama used BBM.
They deserve to be sued by their former customers. This underscores why Apple and other tech companies need to resist against building such backdoors into their products.
Every other week I hear about some malicious app for Android or so. But this is crazy, at a whole different level!
This new page on Apple's website shows how the signal drops whenever you hold a smartphone in a certain way. The whole thing seems kind of surreal to me.
