BlackBerry says BBM for Android and iOS won’t relaunch this week as blocking leaked app ‘will take some time’ - The Next Web

The team is now focused on adjusting the system to completely block this unreleased version of the Android app when we go live with the official BBM for Android app. We are also making sure that the system is reinforced to handle this kind of scenario in the future. While this may sound like a simple task – it’s not. This will take some time and I do not anticipate launching this week.

This smacks of a considerable level of architectural inelegance. With all the experience the industry has in access control and registration, the pre-release cannot simply be blocked by version number? Maybe these guys should have a drink with Mozilla developers - forever adept at blocking old addons from Firefox with incredibly simplistic logic. That this wasn’t thought of in the case of BBM is shocking. What kind of massively deployed messaging system would not ship with a method of blocking unauthorized clients, or at least a group of admins clever enough to accomplish it? Sometimes I worry about the future.
