hi, i just got my new 3gs and i noticed that the colors are dull compared to my old 3g. i just also noticed that wen i use it then turn off the screen then back on it seems to almost fix the colors a bit but it dulls back up after a while. Basically it fluctuates. when there is black color on screen is looks grayish almost. can i return this to apple store where i bought it with out problem? thanks and the apple store i bought it from still has plenty in stock.
