iMessage was introduced along with iOS5. In my opinion it is one of the top 2 features of iOS5 (the other being improved notification system). It’s Apple’s answer to BBM service.
Follow the tutorial below to setup and use iMessage for your iPhone.
• First thing ensure that the iOS 5 is running successfully.
• Go to ‘Settings’ & select ‘Messages’ then turn the toggle switch for iMessage to on.
• Now there will be a message called “Activating”.
