Lately I've been playing with the idea of upgrading my laptop with a 3G modem. The one Fujitsu-Siemens uses is the GTM378 (as seen in the web-configurator), which is available on many auction sites including ebay.
My laptop came without 3G, but having looked inside I know it has both the antennae and the SIM card slot. The question is: Will it work? With reports on thinkpads needing a BIOS hack to get "unapproved" WLAN/WWAN cards working, I'm not yet ready to take the plunge and buy the card. Are there any users who bought such a card and got it successfully working?
And while I'm at it, why limit myself to the card FSC would supply anyway? Apparently Option offers more than just the 378, there are HSUPA-capable cards available. Anyone who's done that?
