Uber's app normally lets users hire cars from their phone, but on Friday you'll be able to hire something much more fun — an ice cream truck. As a way of celebrating National Ice Cream Month, an ice cream cone icon is being added to the app, which lets you request an ice cream truck to a specific location. You'll be given a timeframe for when the truck should arrive, and your credit card will be billed $12 for a bundle of five ice creams. What kind of frozen treats will be available depends on your location — the trucks will be in Boston, Chicago, New York, San Francisco, Seattle, Toronto, and Washington DC — but Uber promises that, no matter where you are, "it's all gooooooood."
