Yoozi!

Yoozi is an online marketplace for buying and selling pre owned cellphones. Only fully functional, ready to activate devices are allowed (no phones with bad ESNs, water damage or cracked screens). Creating a listing to sell is free. Simply select the device being sold and describe what's for sale, including the device's condition and included accessories. Yoozi provides a streamlined experience for buying and selling gently used, fully functional cellphones.
