How Text Messages Are Stored on Palm Centro and possible recovery

Question

I come from an extensive IT and programming background with emphasise on databases.  I need some high level understanding of the text messaging system on a Plam Centro system with ATT.
Questions are related to Recoverying Deleted Text Messages
1.  Do all incoming and outgoing messages get written to the messages_database.pdf on a Plam Centro (ATT)?
2.  When a message is deleted, would it be correct to say that the message is not physically deleted but just that a record pointer in the database (messages_database.pdb) is reset so the messages appears to be deleted?
Why I ask, is that I see a many many requests for people (myself included) of wanting to recover deleted text messages. (i.e. my 16 daughter will not email now becuase we check email but she does text unknown people constantly and it makes it very hard to keep her safe).  When she syncs her phone with her computer, the messages_database.pdb file is in the backup directory and if you open it with a text editor (notepad.exe) you can see only messages that have not beeen deleted.  She usually deletes all her text messages.  There is A LOT of extra data that appears to be encrypted and is not readable.
Is it possible that the text messages are there but just that the database record pointers hve been reset OR are Plam text messages written to RAM some how; although that does seem to be the case, since when you sync, the messages_database.pdb files has any and all messages that have not deleted.
It woul be VERY valuable (and I think profitable) if someone very high level knowledge of the messages_database.pdb file could write a PC application that would alloow you to undelete the text messages.  I know there are programs out there that can do this on SIM cards on systems that write the text messages to the sSIM card, but it is my understanding that messages are not stored on the SIM card but in RAM.
Can any high level technical Palm programmer shed some light on this for me and let me know if there is a way to recovery deleted Text Messages on a Palm Centro?
Much Apreciated,
Greg

Answer 1

 I    had the same problem.
1.Search for a program call filez.prc (give your address I can send you) copy it to a memorycard. btw [email protected]
2. Copy it to the palm device(it works on any)  activate the program on the palm chk rom at the top and chk all message database and smstxt and also some have 0000behind em.  note the sizes as the older ones are larger and copy them to the card.
3. to view em use microsoft word and use recover txt from any file I think it is called. You will be able to see detail but be careful as it sometime displays truncated or mixed but you will be able to see most txt clearly.
