Ya, I don't think BBM will survive on IOS if it isn't the full version. The reason people like is because it's got things like group chat, which whats app does not have, it also allows you to update your picture and stuff like that.. it's like a mini facebook for people on BBM.. I have an iphone and a BB for work, and the BBM is so good for having the groups option, we have different chats just for police road blocks with like over 100 people in it, so if you see a police road block, you zap it to BBM and everyone else knows..
