It suffered delays after an unofficial Android version was leaked, but Boulben said the issues that caused it have been fixed.
'Best in class'
Lately BlackBerry's had its lips sealed when it comes to BBM for iOS and Android, but Boulben's willingness to open up a little could mean that it really is almost here.
His hint came after BlackBerry published a letter on social media and in 30 newspapers around the world assuring customers, "You can continue to count on us."
In the letter BlackBerry called BlackBerry Messenger a "best in class mobile social network."
"There are already around six million customers pre-registered to be notified of our roll out," the letter said.
"This number is growing every day, and speaks to the tremendous opportunity we have to expand BBM beyond BlackBerry smartphones to make it the world's largest mobile social network."
Last we heard, the Android and iOS BBM app is expected to initially feature messaging and groups, with voice, screen share, video, and other features being added in later updates.
It's unknown whether that's still the case, but it sounds like we'll find out soon.
