I am on iTunes 11 and I was recently forced to upgrade my iPhone to 6.1.3 due to a corrupted sms.db file. And even after restoring my iPhone 5, it still has lost all of my text messages (about 4 years worth - I rarely delete them). I was going to restore from an earlier backup of my iPhone, but I have spent hours looking for the MobileSync folder and I cannot find it anywhere on my MacBook Pro. It used to be here: ~/Library/Applications Support/MobileSync/Backup but that folder doesn't exist. Does anyone have any idea where I would find the backup files for the iPhone?

Thank you
