ummm unsure about that on button not working however if the price is right i will bid *nothing over 4000 but you should do free US shipping@ when you reach a certain amount of bids
(advice to seller) if you post photos of the phone with a note beside it saying you are new to listia and put your user name on it you will build confidence with the ones bidding that you actualy have this and you will get more bids. also post lots of pics of the items you list from multiple angles.
