The BlackBerry Curve 8530 for Sprint features technology upgrades from its predecessors including 3G, a memory card slot that supports up to 32 GB microSD memory cards (2 GB card pre-installed), dedicated media control keys on the top of the phone, and an optical trackpad. Replacing the traditional trackball, the touch-sensitive optical trackpad technology offers the same navigational function as the trackball but is more reliable, flatter, and quieter.
