Meta-Doctoring: Part 3 - Sprint PRL Backup
What is PRL you ask? Good question. I don't really know either. PRL stands for Preferred Roaming List. Is is a database that gets downloaded to a smartphone that uses CDMA radios just like the ones in Sprint and Verizon Pre/Pre+ phones. The database has a list of network IDs that Sprint has network sharing contracts with to allow your phone to "roam" on other carrier's network towers. (source)
The good folks at webos-internals.org have a wiki page up on how to backup your PRL data before you go ahead and do the meta-doctor webOS 2.1.0 upgrade.
Just an important note: You must use your own PRL data. It is tied specifically to your phone!
