Wondering if anyone had used "The Walk" on an iPod Touch 5. The concept of The Walk (and Zombies, Run!) is cool...kind of make a game out of a physical activity. I don't really want to risk wrecking my iPhone while I'm out walking around, would prefer to use something cheaper in case I drop it or whatever, so wondering if the iPod touch 5 would work... It's listed as compatible, but that doesn't really make sense to me as the game uses GPS, which the iPod lacks, sooooo....?
