So if you're in India, the government/authorities can read everything you send on your Blackberry. And that includes BES. I wonder if that includes BES servers that are located outside of India. Now wait for other countries to follow. RIM can't ignore India since it's one of their fastest growing markets.
Under the new setup, RIM has said it would not even remotely monitor its Mumbai facility anymore, and has agreed to 'disconnect the remote maintenance system monitoring which it normally provides to ensure high service level'.
As an overview: NO they have not "handed over the encryption keys" for BES and as far as BIS, the Indian government now has as much access as they have with iPhone or Android.
Si.
EDIT:
Oh for f*ck sake. Did the OP actually read the article which he's posted?!?! It CLEARLY says in the article (I've underlined the important bit for the OP): "But he said there was no access to secure encrypted BlackBerry enterprise communications or corporate emails as these were accessible only to the owners of these services."
