I have an iPod Mini 32GB and I put a blue case on it. It shows up as green (old colour) in iTunes and I was wondering if there is a way to change that. I know it's a very minor issue, I'm just curious.
I've found the solution: images of all devices are stored into iTunes.rsrc (/Applications/iTunes.app/Contents/Resources/itunes.rsrc)...i've changed my iPhone 4 32Gb black into a white one (png 4484). To open *.rsrc i've used theme park 3.1.
