Yea, it happened when I lost a signal in the basement at my work. After driving round town and flipping between auto prl and LTE I was able to get 4G back.

Ummm.... I thought the thunderbolt had an independent EVDO radio, and thats the reason it does voice and data at the same time. When eHRPD went down in my 3G only area I was still able to surf and talk. I wonder if the charge is dealing with the same reboots, if so then it has to be something...
This is a speed test I took while in said meeting. Not to impressive, but LTE isn't even live yet, so can't expect too much.

I was in a meeting today on the SE side of town, and I had a full 4G between 1 and 2 this afternoon. Their getting close, one of these days the 4G will come on and stay on.
I got to play on 4G today during a testing in Colorado Springs and it was stupid fast, then poof...gone
The past hour or so my phone's been flipping between 3g and 1X, come on 4G.
