yeah.. iMessage is built into messaging itself and all you need is to activate weather with the service provider or add ur email id to work with. As iCrank said it only works between 2 iOS 5 users with email ids too so if u wish to check then u must add email id of ur fren(who have iOS5) on ur contact list then use send message option on contact ilst itself. If u like to try then u can add me (
