This is follow up to the previous post about iPhones internet power and SMS text messaging (the power). With the launch of the app store AOL has led the way with its AIM iPhone application. Twitter and Pounce also followed with their own apps. But AIM has had the capability to send SMS text messages and so does the iPhone AIM application as this lifehacker.com article and others have already described. Of course, the really cool feature is it doesn’t cost you any extra to send SMS text messages through AIM. Then again, you could just use AIM to chat, or twitter, or pounce, or Google Talk, email, or even call them. While SMS is the only one of these at the moment that can interrupt your workflow, not being interrupted may even be a better side-effect of not using SMS.
