I own a Nokia 3230. I feel that its getting dirty. That is dird is being accumulated in b/n the switches nd joystick. I think it can be easily cleaned by removing the cover. I want to know if Im voiding the warranty if I open it(only the case/cover). Is there any other attractive cases available...
