I've done all sort of searches on WAN cards, Express cards and couldn't find a thing. So being a bit of a newb to this, logic would think that I can take my sprint merlin 720 card, plug it into a usb to express card adapter, and then plug it into the N800 via a host cable and I've got wireless all the time, no? Thinking I'd need a dual cable that I could plug into a portable power supply to sufficiently power the card. Since my Centro won't connect, and I don't want to carry my laptop, this seems like a relatively simple and effective solution to always have wireless connectivity.

Thoughts?
