I think you're only option is a restore from backup to get the old SMS to the new phone...
However, you could try deleting everything off your current phone so that the only thing that remains is SMS, do a backup then restore that. Maybe that'll work???

It's the only way to get it back on there. Other methods will have you extract it and export into a document. The backup isn't iPhone specific. It is just all your preferences and settings and your data that you want to retain. There's nothing about it that makes it only "3GS" or that it works best for 3GS or that it will be upgraded to work on 4S. It is just data. I have upgraded from my backup since my iPhone 2G (2007) and I haven't had a problem. By this logic, my 4S has different devices in it now (2G, 3G, 3GS, 4).
