No problem omegaend, I just mentioned it because the WIP section contains thumbnail images for work and starts to look messy without.

What you are looking for if you want to make a detailed inside of a mobile phone are the blueprints which i can almost guarantee you will not be available on the internet as they'll be protected. Here's the best link i can find and it's only photographic refs.

Why don't you make a clip phone instead, then you can animate the rotation for open and close. It will be more interesting, because the inside bits of a mobile phone are quite ugly, that's why you never see ads of the animated assembly I think.
