Dual BBM, have 2 BBM in yor 10.3
need 10.3.1.
this is old version of BBM, no sticker, no channel, just basic chat.
and need rotation lock, landscape will crash the app.
why use 2 BBM? real one is for private, and sideload one usefull for bussiness which often broadcast for new product and ads.
tested on Z10 10.3.1.2072 and newer.
