The second reason for upgrading to a BlackBerry 7 OS powered phone is the "Fast Fluid Graphics" found on the operating system. This brings new icons that are more visually attractive and have smoother transitions. The hardware is more powerful and the higher resolution screens allow for a better user experience, according to the Canadian based manufacturer. Photos appear brighter, games run smoother and the scrolling gives users more satisfaction.
