I had this listed on eBay and it sold for $390 but the buyer seems sketchy (by the time I checked the auction they were no longer a registered eBay user) so I cancelled the bid, last bid before that was $381 and he never got back to me. So, for sale for $360 shipped firm. I used it on T-Mobile but you can use it on any GSM/GPRS carrier (t-mobile, at&t etc.):

There is a small scuff on the bottom corner, other than that its in great shape.
