I have permanently solved the double sms problem (for myself at least).

*MY* problem, which has identical symptoms to other peoples is described above. This was my solution and reasoning;

I figured that it was very unlikely that it was a bug in the OS, so I looked elsewhere. Mirage; do you have Beautiful SMS installed?

The Beautiful SMS widget sets up its own notifications when you create the widget on your home screen. The notification is IDENTICAL to the stock sms app, and points to the stock messaging app too. When you remove the widget, the notifications remain in place. Every time you receive a message, BeautifulSMS will notify you. You can fix it by creating the widget again, and disabling sms notifications in the widget's settings. Or just uninstall the app.

Other SMS widget apps may have the same or similar icons. lol.

SOLUTION: Check your widget's notification settings. (eg. BeautifulSMS, SMS Popup.)
