3 screenWhile most American cellphone services are still trying to figure out a pricing model for music downloads,  U.K. carrier 3 has come up with what looks like a sensible one: pay once, download twice. The company's "dual download" service lets you download the same song twice — once to your phone and once to your PC — for one fee. Sure, the fee is £1.50 ($2.64) per song, almost double the 79p ($1.39) per song iTunes charges in the U.K. But at least you can download directly to your phone, something you can't currently do with the Moto ROKR E1, the only iTunes-enabled phone.
