One of the coolest new features in iOS 5 is the inclusion of iMessage, which is similar to Blackberry’s messaging service and allows anyone using an iOS 5 device to send and receive messages over the iMessage network.  This happens independently of carriers and their texting plans, and is completely free.  It also works automatically, so that anytime messaging takes place between iOS 5 devices, iMessage is used.  

In order to activate iMessage, go to Settings, then Messages, and drag the iMessage slider to the “on” position.  You can also activate read receipts and have it show a subject field if you like.  iMessage takes iOS 5 users to the next level of Apple mobile services, even though the premise is nothing new.  RIM has offered its Blackberry messaging service for years, but this is the first time the iPhone, iPad, and iPod Touch have gotten in on the action.
