Sorry, I should have been clearer. The registration date came from the whois search. In the linked thread, the provided phone number was called and it was a dead end, although it seems to be different than the one you gave.
Seem to be too many contraindicators to me. How much less than an official Apple refurb is this? Not worth the difference in price. And look what else pops up on their site... $200 unlocked 3G iPhones? Please....

Just walk away. (In case I'm being unclear again, there is no unlocking mechanism for the 3G iPhone to date, and even if they are sold SIM unlocked in some countries, there's no way they're going to be bought there, have their contractual fees taken care of, transported to the US, and sold at $205).
