granted i get the irony of BB asking that Apple open up imessage after how they handled BBM but they might be right.
BB's missteps with BBM should be a warning to Apple that having a closed messaging system might not be the best thing.
there could be benefits for apple...opening imessage could potentially bring iOS more customers. much like what itunes did for the mac. Also it slow down the adoption and growth of other messaging apps.
if apple wanted to turn the messaging business on it's head it would release a whatsapp-like messaging client, compatible with imessage, to all the other platforms.
by the time bbm didn't it, it was too little too late.
I believe that messaging should be an open platform much like email. I like the idea of not having to worry about what platform i'm using to talk to people.
and one more thing...Apple could merge imessage and facetime and really give consumers an all in one communication client.
but unfortunately, Apple is a hardware company and I surmise that they veiw giving other platforms free software would hurt their hardware business.
making itunes cross platform, if anything, should debunk that notion.
