Can the new POWER Vision phones be used as modems just as the first generation 3G phones (Sanyo 8100 and 8200 etc). Can the Samsung MM-A920 or Sanyo MM-7500 be used as a modem with the correct cable? If so, what are the speeds one can expect to see? I see Sprint is offering a Power vision package that offers unlimited internet for $25 a month. I'm not interested in using it on the phone itselft. I will need to connect this to a laptop. Thanks!
