BlackBerry's messenger service may finally cross the platform bridge in the next few days.

BlackBerry Messenger is reportedly set to make its debut on Android this Friday, and become available on Apple's App Store as soon as Saturday, according to BlackBerry news site CrackBerry.

It's been a bit of a wait since BlackBerry announced in May that its messenger service would be made available across different mobile operating systems. By going cross platform, BlackBerry hopes to compete against services such as WhatsApp, which boasts more than 300 million users.

A BlackBerry representative declined to comment on the rumor.
