After the Jailbreak of my 3GS using JailbreakMe.com I tried to restore all my previous Jailbreak Apps. But unfortunately the / partition of my iPhone was quickly out of space :/ and I wasn't able to install all my apps.

Fortunately someone created a little script to free this partition up by moving some system folders. Now I have 101MB of free space on it

Thanks to the author of this script.

Here is a little how to:

1 - Add this repository : http://biteyourapple.com/fmi

2 - Install FreeMyiPhone, it will install a script file "fmi.sh" into your /var/mobile directory

3 - Open the terminal, type su and then your password. And execute the sript "./fmi.sh"

4 - Follow the instructions, BUT DO NOT REMOVE Text input AND Carriers
