Quad band GSM usually refers to the 4 main GSM frequency sets used throughout the world. In other words a quad band phone can pick up a signal on any continent as long as it is unlocked to accept those signals.
Dual band 3G support refers to 2 antennas designed to pick different ends of the 3G spectrum so if one fails the other can take over resulting in better call quality.
