I have an iPhone 3g that i purchased 2 weeks after they came out. I have noticed a blue dot on my screen that is very apparent sometimes, and other times its not even there. I believe this is referred to as a frozen pixel. What do you suggest i do about this? Do i take it to an apple store and hope that at the time of my appointment the frozen pixel is visible? If i do this, and the pixel isnt visible, i guess im out of luck. If it is visible, what is their policy for something like this? Thank you.
