iPhone's announces BBM Competittor "iMessage".

A new service from Apple called iMessage, that is pretty much identical to RIM’s BlackBerry Messenger client has been announced at its World Wide Developers Confrence. iMessage will let you send and receive text messages, photos, and contacts from other iOS users. Group messaging and read/unread/typing notifications (which are staples of BBM) can also be found in iMessage.

This could be really bad for RIM(Blcakberry) as the Blackberry Messenger is a massive selling point for the Blackeberry phone. Let's see how it goes.
Go Apple!
