At Apple Press Conference, we have heard about the white iPhone 4 which will available soon but now it was delayed. Regarding to the reason of the delay, we have learnt that 21st Century Herald is having difficulty reliably getting the right opacity and thickness for the pure white paint that Apple wants on the glass panels. Finding the best suitable glass panels for white iPhone is really hard and maybe there are only half of the total need of Apple so it is better to postpone.
It is really the hard time for Apple. Seem like there are more and more unexpected things are still around including antenna reception problem, reacting from its competitors and delay of white iPhone.
