iPhone/iOS Backup Extractors

Taken from: http://supercrazyawesome.com/ ; What does it do? This application converts the iPhone / iPod Touch backups that are created by iTunes into readily usable Mac OS X files. It is designed to run on Mac OS X Leopard only. What's it used for? Extracting application resources for developers to help them investigate bugs. Exploring files that are created by third party applications using Finder. Decoding the SQLite database files that are stored on the iPhone / iPod Touch, such as Call History, SMS messages, and Notes

The other iOS Backup extractor that I like to use is iScavange.  iScavange has an easy to use interface and is simpler to understand for novice users.
