Okay so I got a used black iPhone 4S to replace my broken white iPhone 4S. I have now synced my new iPhone to my Mac and done all the updates but I'm still missing a years worth of text messages. The latest ones are from early 2012. I always backup to my Mac as I don't use iCloud and a backup always happened when I synced and charged my iPhone to my Mac. Where would those text messages be and why did they not sync to the new iPhone??
