This thread is so full of fail it hurts!
What you're talking about is a basic function of an iPhone (backup/restore)
Boggles my mind that a large portion of the iPhone having population doesn't even know how to use it.
I'll have to admit that I forgot the standard iTunes backup did the SMS log also. I'm so used to iTunes backup sucking in so many other ways, I was confused.
Like, for instance, why it keeps backups from months ago, yet often only one from recently, yet iTunes fills my recycle bin with copies of old apps that have been upgraded and I can't officially do anything with the copies.
