This problem used the same file as before, but had a different goal:
A friend asked the user to reset a password via SMS. What password did he set it to?
Hmm, so this time we need to find and read the user's text messages.
A quick google search suggests to check where the database file is with the following command:
$ find . -name "*mmssms*"
Now, opening mmssms.db, we see it's an SQLite database with the user's text messages in plaintext!
I used the Firefox extension "SQLite Manager" to browse through the messages in the mmssms.db file, which eventually led me to the password, seeyou2morrow.
