Thought for the day (and all following ones :-)
Inform yourself before updating to a new version of OS X, iTunes or firmware!
More often than not, an update breaks iFuntastic and/or jailbreaking.

Take a Moment to Pay Tribute
to the iPhone Dev Team without whose efforts and tools the iPhone or iPod would be a lesser device...
Thank you, Dev Team, for your brilliant hacking - in the good sense of the word! Kudos to GeoHot for his work as well.
Their tools do the all important jailbreak (and more) which allows full access to a device's file system.

Download Jailbreaking Tools
Please understand that I cannot give support for the jailbreaking tools.
There are assorted conditions that should be met before running any of these tools and different possible complications.

You can find answers to many questions online.
Here are some links:

For the most up-to-date versions and information check the iPhone Dev Team blog, and GeoHot's blog.
Excellent guides (and downloads) can be found at Hack that Phone.

Please pay attention to the exact device, operating system and computer requirements!

Jailbroken but still Shackled!
Some of the tools (e.g. blackra1n) do not install the AFC2 file service which iFuntastic needs for full read/write access.
If your device is jailbroken but iFuntastic still shows the status as 'Shackled', then that is most likely the reason.
Use Cydia to install afc2add (if available.) iFuntastic should then show the device status as 'Unshackled'.


If you need assistance to put your device into DFU mode to restore, you can find it on the Utilities & Troubleshooting page (and tab.)
