Does anyone know which WWAN/UMTS/3G work in a T520?

I'd prefer to get a used item and/or some slower card (like the older 7.2mbps cards), but since Thinkpads whitelist those cards in the BIOS...
I tried to find the information on the Lenovo homepage, but I couldn't find anything

Cheers mate!
Sorry for taking so long to respond.

I don't feel comfortable flashing a modified BIOS... I have to think this over.

In the meantime, if anyone knows which cards work with the original BIOS I'd appreciate if you let me know.

There is a list in the T520 Hardware Maintenance Manual, but basically for "Western" users..... its either a Lenovo supplied Sierra Omni 3000 based card or a Lenovo supplied Ericsson F5521gw card.
