We aren’t going to run through the complete play by play, however, to make a long story short, Research in Motion still hasn’t adequately addressed India’s department of telecommunications (DoT) concerns about security on the BlackBerry and thus faces a potential ban in the world’s second largest country.

The DoT wants a monitoring solution that will allow them to read the encrypted messages sent between BlackBerry devices. RIM’s solution addressed BlackBerry to Internet communication, however, BlackBerry to BlackBerry messages are still encrypted. RIM had been given a 15 day deadline to come up with a solution, however, RIM and the DoT failed to come a consensus. Both parties decided to reconvene again on April 21st.
