Ok - so my biggest issue with using an Android device full time is the simple fact that in my house, due to our radiant barrier, we don't get very good cell reception. When it even works, its weak and spotty. Calls aren't that big a deal as my wife and I rarely call each other or other people from our house - however, its extremely frustrating not being able to text back and forth or have messages get stuck. The iPhone fixes this perfectly for us via iMessage. Now my wife won't ever leave her iPhone unless I somewhat force her to, so that part of the equation is static. My question: is there any app that would allow me to text my wife via wifi that doesn't require her to download or use a different app? Major props to whoever can figure this out.
