I'm pretty sure a guy on Front Runner this morning had a Galaxy S6 Edge
It had the weird curved side with his apps along the "edge". I had no idea what it was other than it said Samsung on it and it looked bigger and nicer than my S5.
I thought it might be a non-US Samsung model until I read this article and the pictures of the S6 Edge looked just like the guys phone. He must be a developer or something. All I know for sure is that I'm jealous and that the phone was super nice.
