If you want to skip the story about how it was lost, found and started beating like the Telltale Heart, fast forward to 3:30 in. There we get another pretty good look at the phone. Indeed it's on Nextel, and indeed it's got Cupcake on board. And apparently it's driven the dude who picked up the thing in the first place to pack up shop and move to a tiki hut.
Peep the video after the break. Again, this one's a little NSFW thanks to some colorful (and not-so-classy) language. So long, Jay.
