If you do a full backup with SPB, it backs up SMS by default. If you then do a full restore, it will restore them as well. If you want to pick and choose what you restore, do a custom restore then uncheck everything but what you want. It gives you the option of restoring SMS or email separately. So when I load a brand new ROM on my phone for example, I usually do a custom restore with only PIM and SMS data. (Even though SPB has a ROM upgrade restore mode, I just like to keep it clean.) I have never needed to turn off threaded SMS to restore. Sometimes it takes the phone a while to thread correctly after restoring a huge message collection, but it gets there eventually on its own.
