Backing up Blackberry text messages to the PC?

Use the desktop software that came with the phone. When the phone is plugged in and the desktop software is running, choose to do a full backup. You can click "advanced" and check for the options of email, texts, call logs.

Joe might well be right, but whenever I have wanted to save text messages I have taken the longer but easier route of just re-typing them into my computer! It sounds silly but there's no loss of authenticity in re-typing them as that's all they are, just text.
