So I finally managed to get the “Nokia Suite” software working in Windows (it doesn’t seem to like an almost fully patched WinXP!) and I have my phone backed up over Bluetooth.
Now, how do I go about deleting 827 texts? I could go through them and pick out the ones from the ex but that would take too long, and by using p3nfs I hoped to do grep -r "ex's phone number" /mnt/psion/C:/Mail/| xargs rm -f but I don’t think p3nfs is stable enough to handle that much traffic. It certainly fell over when I tried to backup my phone using it. I’ll give it a go tomorrow, it might work! Anyway, deleting her number from my contacts is a lot easier! 
If you know of any 7650 app for doing mass-deletes of text messages please leave a comment!
Update! Just figured out that I can “Mark All”, and I then delete the texts with a few clicks of the Option button. Sorted!
Look what I found today!
