iPhone 3gs 8gb slight fault ?

iPhone 3gs 8gb good condition no box slight fault is that the wifi does not work for some reason. Im no expert so Im not going to attempt to fix it so spares or repairs. Will be good for an ipod if it cant be fixed. Locked to 3 may be able to unlock but its beyond me. The phone has been reset and is at the configure screen like it is when you take a brand new one out the box. Text only please as Im at work. Thanks for looking
