Save SMS texts to Gmail from your Android phone

I had a lot of very important SMS messages and I wanted to save them - but how? I have an HTC Hero with Android, I went to the Market and downloaded SMS Backup by Christoph Studer. It uploads your SMS messages 100 at a time (you can change this if you want). They appear in your Gmail with the label SMS. It works very well. The other nice feature is that it can automatically upload your SMS texts to Gmail as you go!
