Try going to ebay and follow soon-to-end auctions of them to see what price the bids win at. That should give you an idea. I checked one site online and found one new and unlocked for $469. Also, do you get the user's guide, home/car chargers or any other accessories such as cables?

one of my friends in my class has an n70, and i guess he wanted a pda or windows phone. soooo, he said hed sell it to me for 200 bucks. is this a good deal? its in great condition from what i can tell, he got a black cover for it too, so it looks really good. thanks
