Softbank has announced a promotion that will allow customers in Japan to receive free 3G iPhones when signing up for a two-year contract. The 8GB version is available for free with a basic, premium or student plan. The 16GB variant costs ¥11,520 (~$120), but customers pay an additional ¥480 (~$5USD) per month on, across a two-year plan, instead of providing the lump sum up front.
