What should I do if I lose my SMS to update iPhone 2.0?

I have a jailbroken unlocked iPhone 2G +. I use outside the U.S., I did. I have had many applications it from the installer, but I removed most of them now. However, now that I can update 2.0, I want do that. Im running Windows Vista 32 bits. I do all the necessary software and expertise. The problem is that I do not want to lose my SMS and other important data, since the last eliminates any day. So what I can do to keep this information to solve? I'm not sure that the iTunes backup, because previous backups for my iPhone (when the restoration of previous versions, like 1.1.2 or 1.1.3) does not work. When arrested and asked if I wanted a new phone or if he make a backup, chose the reservation and the iPhone has become full (8GB maximum) when there was nothing. I do not want software solutions .. without a computer!
