BlackBerry (The Company Formerly Known as RIM) could've had BBM out for Android & iOS as well as Windows Phone months ago, had they used the IDE called Codename One, as you can code for all 4 smartphone OSs at the same time!
I love BBM so much more then Whatsapp as you don't have to give out your number and it tells you when a message is delivered with a D and read with a R. The 2 check marks don't have anything to do with that if you didn't know that already.
@ otacon72 I with you on that "Android has more security holes than Swiss cheese" Carrier-installed ‘Carrier IQ’ spyware found in Android, iOS; should we panic?
I believe this happen last year or so and with the new "iPhone 5" they removed it Back Berry don't have such applications install, then again I could be wrong.
