When I upgraded to the Torch from the Storm, I listed it on Craigslist and Kijijji. I sold my Storm, with a bbskin, and my old bluetooth headset for $250. I paid $179 for my Torch + $40 for a new bluetooth. So yes, there certainly is a market for used Blackberries. Many people do not have phone insurance, so when they lose or bust their phones, they are stuck in a contract with no device. A replacement can cost them $500+ for a new one. List your berry, and give it a few days. Mine sold in 48 hours.
