Apple today unveiled their BBM clone called iMessage available in iOS 5. iMessage will have similar BBM features like delivered and read receipts, photo and video sharing, group chats, and more. There have already been 3rd party attempts at cloning BlackBerry Messenger, but none have come as secure or fast as BBM. It will be interesting to see how well iMessage’s performance is compared to BBM. This is the first attempt by any of the top mobile OS players to copy BBM, do you think they’ll succeed? Will iMessage negatively affect BlackBerry’s attractiveness? Vote and sound off in the comments!
