whenever i fail to sell something on ebay within 7 days... i do an item search for the same item i am trying to sell, and then along the left side of the screen there is a box you can check to show only completed listings.
then, you can look at phones like yours that already sold, and compare the most anyone got for one to the least anyone got from one, and maybe use that to help you determine a new asking price.
looks like a good phone, your feedback is good, i don't know what price range these phones sell in but i dont see any reason that you can't sell it if the price is right. here is the link to completed phone listings, hope it helps!
