Jason Mraz “I’m Yours” Played on a Cell Phone? [VIDEO]

I can't even play this song on the piano, much less a devise that was only meant to make phone calls.  This kid had WAY too much time on his hands.  Plus 2 outdated bottom tier cellphones.  What to do...how about make awesome music.  Melody is on the right cell phone and the rest on the right.  How do people come up with this stuff?
