Nokia N85 — Failure model

i am from singapore. i bought a N85 Phone for S$540 ( in two year post paid plan). some settings i cant change. i cant mute the camera sound. display also very dim. there is not veriety of themes. we must download it. phone is block colour and the display also block. so i ask for change other models . but the shop owners refused. i cant satisfy with the phone. so i sold it to other person for 475 S$ only. normally original prize approxmately S$700. if i keep the phone long days, the resale cost come very down. so i sold immediately.
