If You've Got to Have a White iPhone 4 Right Now...
The white iPhone 4 is set to be released in 2011, but that does not mean you can't make your own now. I've seen many requests come through for white iPhone 4 conversions. Sometimes this happens because somebody has already broken their screen or back cover, and other times simply because people want it and they want it NOW!!!
