Out of curiosity, has anyone added a WWAN module to their Fujitsu Lifebook/Stylistic themselves? Do you have to buy the one Fujitsu sells, or can you install any WWAN module found on eBay, for example? I've read that some other manufacturers (HP was one of them I saw) incorporate checks in the BIOS that only accept certain WWAN cards (i.e. only those from the OEM and not any third-party ones). Some cards go on eBay for only $30 or so, whereas the Fujitsu store one goes for well over $100!
