Ok, serious face now.
From what I understand, when a PRL gets updated, it changes the order of cell towers to grab the signal from(to achieve the best possible signal), and to grow accustom to the new roaming contracts between carriers.
In a nut shell, say Sprint is your carrier, and the PRL gets updated, it will try to grab the best signal from sprints towers, but also search for better signals from other carriers, and start roaming.. however, if say, Sprint cancelled their roaming contract with Verizon, then it will no longer search for a signal using Verizon's towers.
Since Sprint, Virgin MobileUSA, and Boost Mobile all use the same towers, you can use any of those 3 companies PRL, as long as it also searches for your native carriers towers (each do have their own separate towers).
(Correct me if I'm wrong, I'm going off of my understanding of what the PRL is, using deductive reasoning..)
