iMessage rivals Blackberry Messenger

Apple has created a new messaging service called iMessage, which is supposed to rival the extremely popular Blackberry Messenger. iMessage allows all iOS 5 users to send unlimited texts messages via Wifi or 3G on your iPhone, iTouch or iPad to anyone with those devices. It is built in to the messages app, so you can also send photos and videos. There is also group messaging, and like Blackberry Messenger, there are optional delivery and read receipts, and you can see when someone is typing. So will this new Apple product rival the much acclaimed Blackberry Messenger? We'll just have to wait and see.
