One of the great fears about geolocation in phones is that we'll all end up living in a Phillip K Dick inspired world where every time we pass a store at the mall we're barraged with text messages offering a coupon only good for the next fifteen minutes. So far, my beloved iPhone has been spared that bit of dystopian drama, but even I have to admit the concept itself is sound. I like the idea of local, timely deals from places I know won't harass me until the end of time once they get their grubby hands on my email address.
