Funny.. I just switched to a GS3 for various reasons and was thinking I wish I could get back the Motorola Email app simply because of what I thought to be an excellent layout. Great threading, and the ability to swipe away emails is a god send if you are getting 100 emails a day.
So with that being said. Any chance you saved the original Motorola APK's and I could try and put them on my GS3?
And for the person above asking about what is different. Aesthetically not too much, just a slightly different color scheme as far as I remember. But loses all the swiping abilities.
