One of the most favored update to be implemented into a new build of iOS has to be Apple's iMessaging system that came bundled with iOS 5 back in October 2011. The iMessage service is Apple's messaging experience on iOS devices, working across the iPhone, iPad, iPod touch and soon to be officially supported by the Messages app as part of the new OS X Mountain Lion operating system coming this summer. The service allows all iOS 5 users to send unlimited messages over a data or Wi-Fi connection to other iMessage users and is bundled as part of the native Messages app.
