Hasn't happened to me and I wouldn't give a **** if it did. The phone remains the best out there and a tiny aesthetic issue has zero bearing on the performance, the feel, etc.
I'm still wondering what these people do with their phones to achieve such a change in color and size.. I'm having mine for over a month now and it still looks like on the first day.
That's only proof that you should not use an expensive phone in cheap jeans or put it in your back pocket and sit on it.
And the next thing you now is them little pre-pubescent Android user running with crayons in an apple store trying to color them phones because it's "justice"
The ones complaining about the dye of cheap walmart jeans coming off and dyeing the antenna bars are the ones who probably can't afford the iPhone go play with your plastic laggy ass boost mobile android device if it's so much better
