CoolBooter is an all-in-one dual booting utility for jailbroken iOS devices
provided completely free of charge.
CoolBooter allows you to dual-boot another iOS install with your current jailbroken iOS.
CoolBooter installs require specific operations which may cause data loss in events
of failure, please ensure you have saved a backup of important data
from your device, and do not use a device that you would
mind needing to factory reset in an event of failure.
CoolBooter currently supports going from any jailbroken iOS (5 or later) to
a supported iOS (5 or later) firmware of your choice on an iPhone 4, iPhone 4S,
iPhone 5, iPhone 5c, iPad 2, iPad 3, iPad 4, iPad Mini 1G, and iPod Touch 5G.
CoolBooter is available by adding https://coolbooter.com to your sources in Cydia.
