cant say i feel the current Bb Os(not BbOs10) is kinda dumb to do that

its more comparable to series40 then symbian.. so dont think there's a chance..

but i would really like to see the answers of other members


EDIT - on second thought.. it might be possible.. if
YOU CAN A MESSAGE FROM BBM BY ACCESSING IT THROUGH BLACKBERRY PC SUIT...

if its possible then N900 might mimic BB Pc suit and Access BBM
