Siemens SX66 / MDA III / PDA2K (HTC Blue Angel)

I know the Cingular SX66 has wi-fi built in, but finding it to buy is another matter. And, the truth be known, I'm a bit pissed at Cingular just now so am looking at Verizon. 👿

Does anyone know if the Verizon version of this phone (Audiovox 6600) is compatible with any of the wi-fi SDIO cards?

Thanks!
