F2, I think you may just be saying that when you debricked, then entered the same BBID as you had originally used, it "remembered" your password. That would be because it was actually logging into the BBID web site, not because it was stored in the device.
Nothing in the device could persist past a debrick.
No, I was referring to the password for my pb (not bbid). I don't recall but there was some initial question regarding password as I was working the debrick. When it came back HOURS later (next morning actually), I got the password screen and it asked for a password. I was surprised but entered the one I had established. And it worked. I am pretty sure that I am not imagining this but .....
