I think I'm going to start a new thread shortly, as this thread has mostly been a trial/error-type of notepad.
I really want to thank ww227, as his method DOES work to get the MSL!!! I was quickly able to change the default SID (4139 which is Kansas City) to my local market of 4418, which made my friend's phone ring immediately instead of 7+ rings.
I HIGHLY RECOMMEND MAKING YOUR SID 0 IF YOU TRAVEL OUT OF YOUR MARKET OFTEN/WEEKLY, otherwise I recommend making it whatever it should be for your local market!
As far as connecting it to QPST to update the PRL, I give up at the moment; ##PORT# is needed to be on USB (thanks again ww227!), but I cannot get proper drivers loaded in Windows XP or 7. I did try my own suggestion at the top of page 2 to possibly install drivers, but alas, those are not the right ones for "JukeB".
