I found a cool utitility to backup your iPhone’s applications, application data, and photos.
This app will really help me when i need to restore again.
The application currently works only with firmware 1.1.3 and 1.1.4 iPhones and iPod touches and it does require you to have jailbroken your iPhone.
To use the backup, download it onto your PC, run the iBackup.msi, install it, and you can either run the program from your desktop, or through your Start Menu.
