I tested this and had the same results. PRL 51540 in place before a battery swap.... PRL 0 after battery swap... *22899 replaces PRL 51540. I will test the phone with the PRL 0 and see how it performs...
might sound really dumb on my part ... but what exactly is PRL ???? What does it do on my phone and why does it matter if it goes to 0???
PRL is the Preferred Roaming List

I started with a battery pull and PRL 0. I drove a loop through my area and watched the signal strength in the status screen. I noted where the signal was good and where it was poor. I then did a *22899 and drove the same loop. With the PRL 51540, I still had good signal in the same areas and poor signal in the same areas as before. The readings I observed were virtually identical in both tests.
Has anyone figured another way to test the PRL in the .230 OS?
were you in 1XEV or vzw coverage? WHat the PRL actually controls is towers that are NOT vzw that the phone sees as 1X for instance I live in an alltel area and work in a vzw area at work PRL 0 makes no diff, but at home with out the prl my service is half or less of what it normally is.. does that make sense?
