I got the iO through my company; the old Director went to a ComputerCity in San Francisco and brought one back because it was so cheap (yah...$199 to buy, $400 to ship next day, early delivery, via FedEx. I wanna be a management idiot too!).
Once they relaized that it wouldnt' work here, they were going to put it in the back and forget about it...so I bought it from them for $50.
Other than that (bringing it over directly), I have not idea how to get one over here. There must be some kind of mail-relay service that can redirect parcels overseas for a price.
Maybe a Mailboxes USA? They also operate as a postal delivery stop as well as a shipper...
