While iPhone users already are familiar with the messaging app for SMS, up until now only third party apps could give similar functionality to other iOS devices. Apple answered that at WWDC today with the debut of iMessage.
iMessage seems to essentially be like a BlackBerry Messenger for the iOS platform. You can send text messages, photos, and videos. Like desktop IM clients, you will be able to see when somebody is typing. Also, your conversations would be pushed to all your iOS devices, and you can choose to enable delivery and read receipts.
My question is now, what about interoperability? Will iMessage languish as an iOS only application with no way to contact the outside world? How about support for other platforms — say AIM — which its desktop counterpart iChat has supported for awhile.
We’ll let you know as we get more details…
