It makes... oh yes...it makes titanium dioxide. Today, I am stumbling on words a lot...(:
I prefer the iPhone 3GS. Primarily because it receives signal better and i find it's easier to hold but that's just me. Plus i like the variety of cases you can get for the 3GS which makes it much more personalised but im sure new cases for the iPhone 4 will come out soon enough!
