More than any iPhone in history, the iPhone 5c is all about color and personality. It comes in hard coated polycarbonate - think plastic, but way classier! - in fun, vibrant shades of green, blue, yellow, pink and white. Color is so personal, so distinctive, but more colors mean more to choose from, and can also mean a more difficult choice! If you're having trouble picking your particular spot on the iPhone 5c rainbow, we're here to help!
there were no changes regarding display color temperature between 5A345 and 5A347, and that there’s no practical reason why someone with an iPhone with 5A345 installed should go through a complete system restoration just to get 5A347.
And that, while there did appear to be differences in "yellowness" from iPhone 3G to iPhone 3G, it was not due to firmware (perhaps components?).
