Sprint's 4G WiMax network was reliably speedy in Las Vegas. Using Ookla's Speedtest.net application, the Shift 4G achieved average download speeds of 1119 kbps and upload speeds of 866 kbps. Sprint just rolled out its WiMax in San Francisco so I'll definitely test out the Shift 4G when I get home. Call quality was very good from the Strip in Las Vegas; callers on the other end of the line heard very little of the madness that was going on around me.
