iOS 5 will include an all-new iMessage service across the iPhone, iPad and iPod touch. The system has a look and feel a lot like the text message app in iOS for the iPhone, and comes with a BBM-style delivery and read receipts, real-time typing indications and looks really great.

Messages are pushed across all iOS devices and since it's all cross-device, you can pick up on the conversation right where you left off when switching from your iPhone to your iPad or iPod touch. The system, of course, will use the new notifications system in iOS 5. Tapping on the notification brings you straight to the new messaging interface, letting the recipient see right when you begin typing.

iMessage includes sending messages, photos and videos right from the camera roll or albums and works over WiFi or 3G.

Apple has really outdone themselves on this one, what do you think?
