    Question sms.db and MMS messages: a question

    I'm trying to read MMS messages (it's a Cydia app! ).

    I understood almost everything, except one thing.

    I know MMS attachments are stored in
    (with ~ = home folder = /var/mobile/ )

    However, what I don't fully understand is how they are divided into subfolders.
    For example:
    ~/Library/SMS/Parts/(group id)/????/(message id)-(part id).jpg

    "07" is the group (from sms.db's message_group; by the way, what happens when this is >99?), 19 is message's ID (ROWID in message table) and 0 is the part id.
    But what does that "03" stand for?

    Does anybody have any idea? I can't find any connection with any value in the sms.db file.

    I thought it was the same as (message id), and before I restored my iPhone (restoring the backup after), it was.
    But then it started again from 01!

    Thanks in advance for your help.

    Ok the "07", "03" etc are hex numbers (so after "09" comes "0a").
    The doubt still remains, though: what comes after ff?
