Recovering data from iPhone backup
Here is a story about how to recover the data from old iPhone’s backups.
As you know iTunes stores iPhone backups in your home directory or more precisely
in ~/Library/Application Support/MobileSync/Backup. The problem is that it’s not very convenient to mess with restoring iPhone and as a result to end up with your current data and configuration overwritten. To avoid that you could use iPhone Backup Extractor program that could do all the hard work for you and restore absolutely everything that is kept in the backup files. It has saved me once when I needed to restore photos from the backup that I had restored from “Time Machine” and hope it will help you one day.
