Sept. 15, 2010 - PRLog -- What is currently best camera phones on the market? I think different users will surely have a different answer in mind. However, the introduction of iPhone 4 have not bring pixel to a whole new level, but it let us deep understanding of the current application of technology and outstanding features huge push for mobile phone camera. Back-illuminated sensors and the HDR technology lets us feel the pixels outside of surprises.
