Sunil Lalvani, managing director for BlackBerry
India, apparently confirmed in an interview with IBN
Live that BlackBerry Messenger will launch on
Android in the next two months. The executive
reiterated earlier statements made by BlackBerry that
the service will launch this summer, however he was
quick to add that in North America summer doesn’t
end until September. When asked to clarify his
comments and whether BBM would be available
before the end of the September, IBN Live noted that
Lalvani’s “response was in the affirmative.” A bogus
BBM app recently appeared on Google Play and
revealed that there is in fact a surprising amount of
demand for the messaging service. The fake app
racked up more than 100,000 downloads in only a
few hours before being pulled from the marketplace.

Don't know about others but this release for me means:

1: I can thrash my blackberry phone which I only need because the cheap internet and bbm.

2. I can have messenger on my android and retain my bbm friends.

3. I can load BIS and use it on my android for unlimited browsing. That is as long as mtn permits.

So who needs blackberry?
