The 4g service was alive in kicking the last time I drove through Cleveland, TN. Not sure if they were testing or not, but it was soild for several miles. There is no mention of Signal Mtn receiving the LTE network. I'm assuming they are not part of this rollout. Does the editor have any info on this? I've had the HTC Thunderbolt for about 6 weeks and the battery is not the greatest, but it does last considerably longer than 3 hrs. The 4g part eats it up rather quickly though, as I've been in Nashville for several days.
