Blackberry - Smart Phone Question

Even better, it is cross-platform (iOS, Blackberry, Android and Nokia). Incidentally, the iPhone now does a similar thing to BBM with iMessage in iOS5.

I honestly thing it is just down to first-to-market (as someone else said). Weirdly, here in Sweden they are really quite rare. 99% of the time if I do actually see a Blackberry, which is almost never, they are being used by a foreigner.

That may not be a description of push email, but the iPhone (and indeed nearly everything else nowadays) does support push email.

In reality, the difference between push email and frequently-polled conventional email is largely semantic - in either case, the client device advertises itself to the network/server, and subsequently plays the receiving part in the conversation that gets the data comprising the mail message onto the device.

There’s quite a noticeable battery life difference between push e-mail and frequently polled e-mail. Outside of that, yes, it tends to be a semantic difference.
