I don't understand why Apple did not disclose all the detailed specifications. On apple site, it only tells the most basic specs not all specs so Wikipedia has to search iPhone specs in other sources.
Have anyone who did use both 3Gs & 4 or 4s? Did u see the picture clearer in 4 than in 3GS?
So which color depth does iPhone 3GS have?
24-bit color or 18-bit color?
