When I dropped mine, I scrateched the front casing and the side rubber thingies. I found the front case on cnn.cn but not the side ones by themselves. Ebay was no help either.
just buy a dummy unit off ebay. or buy a entirely new housing
are dummy units disassemblable? haha is that a word? I just got one off ebay in hopes to replace my titanium faceplate for my 8320. we shall see i will let everyone know
