I did a poor job of explaining what I meant the first time around. We have noticed multiple sites that go 3G NV live without the backhaul connected to the site. What this means, backhaul is at the site, but they do NOT switch over to the new backhaul until they launch LTE. Does that make more sense? I.E. It is still possible that the site will go LTE live in a couple days. However, we have also found that there is no real indication as to the timeline. It could still take a month or a year, you never know.
No, bands have nothing to do with PRL. PRL is only a roaming list. Your phone either has Band 25, 41, 26 or it does not. No PRL will fix that.
