From poking around the archives at XDA, I would guess (just guess) that my phone isn't "CID unlocked" and I can only flash a ROM which matches the provider currently on my PPC. Color me confused for now...I thought the phone had to be 'locked' to load the base 3.16 ROM? Or is that a different kind of "lock" and I'm mixing apples and....different apples??
Here is the post that is hauntingly familiar:

I might have to get mtty and start poking around...look out world....
