just done the update to the latest bb10 software and bbm disappeared and in app world showed as downloading, then it stopped and said it was canceled
I also have nothing on app world??! may be the it policy the phone is on that has caused that? I am not so bothered about the other apps just need bbm please. I have scoured the net and cant find the bar for bbm
BBM is built into the operating system i dont believe there is a bar file in existance something might have gone wrong with the installation. i would try a hard re set hold both volume buttons and wait for a reboot if it doesent appear start over again.
