Help me Modify my Nokia N-Gage

Hey i have a old Nokia N-gage classic which i bought around in 2001. Now its working perfectly fine but it has some small damages in it such as the glass on top is cracked and some scratches thats all. I want your help to help me out to find cool things or designs to make mu phone into. Description: So basically i want to make my own plastic or fiber glass case so cool that it makes people say woo...thats new...(because i can't find the cases anywhere now in fiji) Also if there is a way i could add some applications to it or some other cool addons. Basically i really need a cool design. and what materials could be suitable.
