Accessibility>white on black
I was just looking in my iphone settings this morning as I was doing my usual Iphone twitter/facebook/rss morning updates and saw under the settings menu then accessiblity the white on black option, flicked it to on and then boom, my screens were drastically changed, I looked it up on apple.com and it is designed for a greater contrast, as most options in the accessibility menu are to help with disabilities or impairments. Looks cool, I may keep it like this just for fun. But if it was posted here before I'm sorry I haven't ever noticed it. check it out.
