Does this mean they can turn 4g up so that it stops falling back to useless 3g all the time?
That comes down to how their handover is configured....
My understanding is that all three carriers currently plan their 4G coverage so it does not extend beyond the the existing range of 3G coverage. This is, again to my understanding, to ensure there are no areas where voice calls (especially emergency ones) are unable to be made due to lack fall back to 2G/3G coverage. This means all along the edges of network coverage there is always a certain amount of area with no 4G coverage at all. As a result phones are required to handover to 3G near the edge of coverage—regardless of how well their handover is configured...
