Proposed SMS design schema

I'm thinking of adding an SMS Tab to BitPim, and this is what I came up so far:

SMS Item Dict:

from: string (email addr or phone #)
to: string (email addr or phone #)
subject: string
text: string
datetime: 'YYYYMMDDThhmmss'
callback: string (callback phone #)

SMS Items will be organized into 3 areas:
Inbox (g)et from phone
Sent (g)
Draft (g/s)

The SMS items would be ordered and listed as 'datetime+subject'.
Phone# and email address lookup from BitPim phonebook would be done when possible.

Additionally, there'd be a fourth area displaying and allowing users to maintain the phone's "canned phrases".

As always, comments and suggestions are welcome.
