Append Text To A Post - PLEASE HELP!

[Patrick Melton]

I've asked this in several ways over the past few months. No one will answer or help.

This has to be relatively simple. I want to append one line of simple text to posts. Basically, something like "Posted from my Blackberry" or "Posted from my iPhone".

I don't need you to program the logic or conditionals to determine what they are posting from. I can do that. I need someone to tell me WHERE (what file, line, variable) I need to append the text to in order to get it on the end of the post.

Basically where does a post get put in to the database, and how can I append a line of text to it right before that happens?

PLEASE SOMEONE HELP!
