Wow. Great run through and explanations throughout this thread.
Serious props to the OP and everyone who followed up filling in the gaps and answering all the newb questions. Sometimes repeatedly. =D>

Been all through this thread as well as the other flashing sticky'd threads and I am still a little fuzzy on the PRL issue.

Do custom ROMs (i.e. dcd x.x.x for Verizon/ Alltel/ Etc) change the PRLs during the upgrades?
For that matter do the "official" ROMs change that before the customizations or as part of the initial ROM install?

I've scanned the Corolada PRL page and my version (00063) isn't available, so I don't want to take a chance of losing mine. I did check with my carrier and they can't/ won't give it up for a backup.
