Nokia N70, Python, SMS

I need a small bit of help: I’m building a PyS60 that needs to be able to send SMS messages. I’m sending the message as follows:

import messaging
messaging.sms_send(recipient,message)

The problem I’m encountering is that this puts the SMS in the Outbox of my [[Nokia N70]], and the application hands until I manually navigate to there on the phone, select the message, and then choose Options \| Send.

Obviously what I’d like this to do instead is “just send the message.”

This doesn’t seem to be something limited to my application: any other SMS-sending Python app I’ve tried suffers the same fate.
