i need to change my nokia 3110c casing.

i own a nokia 3110c for 2 years now and the casing is not in pretty dandy now due to heavy use.

if i can change the casing where should i go and how much may the price will cost me, and i prepare to change it by myself.

already went to nokia center and the charges are not quite good for me.

any cell-shop selling chip casing for my nokia 3110c out there?

send me the price and the name of the store and the location @ 0922-298-6628. thanks...
