Taking some cues from the ideas section of the BGBB I have made the following updates to Progia-11s.
1. Anyone can delete all the messages on a progia-11 from the messages menu.
2. It is not possible to perform a 'factory reset' which deletes all contacts and messages, and has the added bonus of resetting the sent message count. That means it's possible to you know, reset a phone back to being brand new (the number does not change) and avoid paying for text messages. To perform a factory reset you use the 'reset' command on the progia. You'll need the appropriate toolbelt, and since you're cracking the OS to do the reset, the appropriate skill.
This does not allow you to view deleted messages, and that's primarily for bloat reasons. Keeping messages around forever costs us in terms of bloat.
Thanks to ReeferMadness for the idea about factory resets!
Long live deckers!
