Let's start one.
What kind of group are we talking?
Then you are going to have to wait. iMessage isn't quite what BBM is, it does phone to phone well, but (from what I'm told) it isn't ready to be a BBM replacement.Oh and the group is just a means of instant cigar (and otherwise) sharing. Mostly a group to stick it to BB users.
it's good, but not great. Definitely a contender if they clean it up and enhance it further. It looks just like text messages but has peoples names on it in the stream. Bad thing is that you can't "add" someone to an existing group. You need to start an entirely new message to add them.looks like you can use email or ph # to send imessage, just have to figure out how to set up the group to get it started.
