When you restore an iphone from itunes backup does it restore messages?

I need to restore my iPhone 4S in iTunes, will I lose my messages or will it leave the messages from my most recent back up?

Backing up is supposed to save:
SMS Messages
Contacts
All Application Settings
Home Screen icon order
Photos taken with the Camera
Wallpaper image
Bookmarks
Calendar Events
Phone Favorites
Voicemail Messages
Notes

It doesn't backup:
Music
Sync'd photos
Applications
Videos

Yes it will restore the messages from the backup.
