finding nearby stores or subway stops? Apparently what's standing in your way from enjoying a life more akin to "gargoyles" from Snow Crash is Apple's next update to its touchscreen devices, OS 3.1, and according to Nearest Tube developer Acrossair, that'll be arriving sometime in September. Something we heard whispered at the time of the beta 2 release. We wouldn't be surprised to see that release window fluctuate, but if that's our estimate, there's still plenty of time for someone to prep an AR zombie shooter.
