Alright so the 200 dollar 3gs iphone 16gb is sold on ebay for 600+ right? Well if it costs 230 to both buy it and activate it, and it costs 175 to cancel a contract with ATT, wouldn't the total cost of the iphone be 405 dollars? Wouldn't I make a profit if I sold it on Ebay? even if I still have to pay the first 70 dollars for that month it would still cost 475...
