iMessage: Everything you need to know!
Complete guide to iMessage, Apple's unlimited text, picture, video, location, and contact sharing messaging service for iPhone, iPad, and Mac
iMessage is Apple's built-in instant messaging (IM) service. It lives inside the Messages app on iOS and OS X. On the iPhone it works alongside — and in some cases replaces — carrier SMS and MMS. On the iPad and Mac it provides similar functionality, allowing you to send text, picture, video, voice memo, location, contact, and other types of messages to anyone else using iOS or OS X. Since there's no charge for iMessage beyond data (cellular or Wi-Fi), you can send unlimited iMessages pretty much for free. Take that, carriers!
Wondering how to setup iOS 5's new iMessage service on your iPhone or iPod touch? Using iMessage you can send text messages, photos, video and much more to other iMessage users around the world, all over your existing data connection. That's right, no texting plans or charges needed! Here's how to get started.
With iOS 5 Apple will be introducing iMessage, an SMS and MMS style service seamlessly integrated into the Messages app that uses your Apple ID and data plan instead of text plan... but only with other iOS 5 users. So lets say you and your special someone both have iPhones, or you have an iPod touch and your mom has an iPad, you can easily use iMessage to stay in contact. But, if you have an iPhone and your husband or wife has an Android or BlackBerry (and you stay with them!), iMessage will do you absolutely no good whatsoever.
iMessage is one of the great new features of the upcoming iOS 5 update and now there is evidence that it may soon be integrated with OS X Lion’s iChat instant messaging software. This would enable instant messaging between iOS devices and Mac computers running OS X Lion.
AT&T has confirmed to Engadget that, as of August 21, they'll be removing all but the unlimited SMS/Text messaging plans:
"We regularly evaluate our offers and are making some adjustments to our messaging lineup.
We're getting tons and tons of questions about iOS 5's new iMessage, how it works, where it sends to, and how to avoid sending to the wrong person or device. Apple hasn't given out a lot of details about it yet, but based on what they showed on the keynote and how they've previously handled user and device ID, we can make some guesses. Now if it looks a little complex... wellafter the break!
