The iPhone has always lacked one great feature found in other U.S. smartphones, and even iPhones outside of the country: the option to buy your hardware outright and operate it on a national network on a prepaid, no-contract basis. Cricket Communications (owned by Leap Wireless) has finally broken through that little restriction with the delivery of a pay-as-you-go iPhone that becomes available through stores starting on June 22.
But not in Chicago or some other big-city markets. Leap’s Chicago-area network uses AWS radio frequencies that aren’t supported by the PCS-only iPhone.
