My wife and I both have iPhones 4's running iOS 5 so iMessage is great for us. I would love to drop our $30 per month texting plan, but my wife has several friends with Android and Blackberry devices. What is the solution, make all her friends install some third paryt app? I doubt I could make that happen. I would like, whatever it would be, to appear native on each phone, that would help. Also being able to fallback to SMS would be nice. Anyone else tired of paying for SMS?
