The iPhone 4 is now boxier, with the rear side now flat, instead of rounded. It will keep the 3.5-inch display diagonal, but will quadruple the pixels to 640x960, making it the highest-resolution screen on a smartphone to date. Apple actually calls the new screen Retina Display, because it shows 326 pixels per inch, while the human eye can only distinguish around 300 ppi. In addition, the screen will utilize the LCD IPS technology (same as in the iPad). The other new stuff includes a front-facing video call camera, 5MP main camera lens with LED flash and 720p HD video recording, Micro-SIM slot, instead of ordinary SIM, a secondary mic for noise-cancellation and a lot of other new features.

  • Technology:

    Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.
