BlackBerry might be in a tough spot right now, but that hasn’t stopped the company from trying to keep up to date on its software. As such, BBM integration has made its way to Twitter on BlackBerry 10.
You can now change your BBM status by tweeting from the updated app. Other additions include thumbnail previews of attached images, a built-in reply box and an updated way to report spam and abuse. Be warned though – the app is reportedly giving some users a bit of trouble, and has outright stopped working in some cases.
Maybe it would be better to wait for the BBM integration in a later update, then.
