t420S and gobi 4000?

[jmg2]

Will This work?
I know the following:
1) it fits
2) The driver recognizes the card

But:
1) it can't connect (even though the card is active on my Verizon account)

Has Anyone had any luck using the gobi 4000 on a t420s? I know Lenovo's party line is that it is not supported. Setting that aside, has anyone managed to get it to work? I'm assuming the reason it's not supported has something to do with the antenna setup (integrated 4g wasn't even an option on the 420s), because it clearly fits and is recognized in the pci port.

Any thoughts? I'm currently using a pantech uml295, but cannot STAND having a dongle outside the laptop...
