Well a lot of you have heard about the new and improved screen on the 7520 so I'm going to show you just how good it is.
These pictures were taken in the complete dark with my digital camera with the flash disabled. The phones from left to right are a 7520, 7510 and 7230.
Pic 1. All phones with the backlight button pressed once:
Pic 2. 7520 button pressed again (the 7230 shut the display off for some reason)
At the second pressing, the screen is absolutely blinding.
Side by side here is how the phone sizes compare. The 7520 is a little thicker.
The 7520 has a real metal bezel around the screen (no more paint chipping!). I have seen one 7230 like it before, but only once.
All models:
Finally, how the black cover looks on the back of the 7520
The cloth underneath is a StarFiber cloth, it is the absolute best thing for cleaning the screens. (No liquid needed!)
