I've been having the same problem as well. I went to the Verizon Store (this was my mistake to begin with) after work and explained the whole disappearing box and not getting the update story. However, the tech assoc. just didn't get it. She relentlessly tried to explain that the update already installed, without me knowing. I called the number listed on the bottom of the update docs when I got home. The tech knew his stuff; he said an internal update was sent everyone last week indicating a small number of thunderbolt owners were experiencing the same problem. Originally his dept. was directing reports internally to an offline dept. that then manually was pushing the update. But he said it was not working out as intended was discontinued. Basically, as of today there is no viable solution. When they figure out a solution, the update will successfully pushed (that and not being required to perform a hardreset).
