Well, depending when he puts it up for sale it may be best to go 1-day. I did 3-day, but the new one just barely came out so it's not that big of a deal I don't think. Plus you've got to think about the international demand for the 1.0 phone. Granted 3g will be in a lot more countries very soon, but I don't think a 3-day auction is the end of the world if you get it up right away. Of course on the auctions that I saw that ended as of last night almost all bidding was done on the last day, so take that for what it's worth.
