MobileSync Browser (MSB) is a tool that shows the backup files iTunes creates when you use it with your iPhone. Everytime you synchronize your iPhone, iTunes keeps a copy of the information contained in your iPhone's SMS and Notes applications as well as your recent call history on your hard disk. MobileSync Browser allows you to use these files for archive or reference purposes. MSB is not intended to be a data-recovery tool, however it can be used for this in a limited way.
