Sprint OverDrive 3G/4G WiFi Router Awesome Little Device: 4G Service Behavior is Puzzling

I took Sprint’s 3G/4G mobile hotspot, the OverDrive, out for a few hours for a test drive this week. If it weren’t so tiny, the hard edged shiny black device which somewhat resembles the Motorola Droid might be slightly menacing looking. As it is, its pocketable size and a promise of easy WiFi access to 3G and, if in the right place, Clear-powered 4G goodness, made it an attractive device to play with instead of actually pursing other productive tasks.
