The Toronto Star is reporting that RIM has agreed to provide the Indian Government with access to the full range of Blackberry communications (RIM gives India access to BlackBerry messages - thestar.com). The article this is based on (http://indiatoday.intoday.in/story/govt-to-tap-blackberry-messenger-security-privacy/1/183403.html) suggests that the Indian Government has been given some sort of backdoor into Blackberry Enterprise Servers, which is something that RIM has staunchly refused to do until now.
If this is true, the era in which Blackberry was the ultra-secure communications platform is over.
This also shows that what was once Blackberry's main strength is also its greatest weakness. Blackberry is a system and RIM controls everything, from the device to the servers. If they compromise one aspect of it, the whole system is compromised. On my Android phone, on the other hand, I can configure just about anything, including what VPN to use and what communications apps to run.
