Boulben said the company already has 6 million Android and iPhone customers pre-registered for the launch of its BlackBerry Messenger (BBM) service.
He said he expects the BBM to launch on both those platforms "within days," adding that the company is confident that it fixed issues that arose after the initial cross-platform launch of the messaging service last month.

Even though the first 'launch' was pooched, I have to say I'm still waiting for its arrival. I still have a lot of friends who use BBM, plus I transition devices quite a bit so having it on all the platforms I use will be great.
