AOL Radio powered by CBS Radio will be available free to iPhone users next month as a part of the iPhone App Store.

You'll be able to listen to all 200+ AOL Radio stations and 150+ CBS Radio stations on the go! AOL Radio for iPhone will work on both the original iPhone and the upcoming iPhone 3G and can be streamed over WiFi or the 3G network. One cool feature includes having your iPhone determine your whereabouts and figuring the closest CBS Radio stations near your area. AOL Radio for iPhone won the "Best Entertainment Application" at the WWDC last week.
