Garf version 0.32 has been out a little while now...it is available on the ModMyiFone repository, which is now one of the community sources on Installer. It will only work for firmware versions 1.1.1 and above.
The main new improvement of this version over the previous one (0.25) is the new skins system. You can now donwload skin packs off of the repository. After downloading, run Garf and hit the Settings button in the bottom right corner. You will notice a "Theme" menu. Tap on it, and then select which theme you wish to use. (Pictured is the "Cartoon" theme, available on ModMyiFone repository).
You may notice that the tones may be different...themes are now allowed to specify the pitch of the sound for each button. They can also specify the button location and button size.
If you are using 1.0.2 and you accidentally install the new one and for some reason don't want to update your firmware, you can get version 0.25 from the SourceForge project page.
To install manually, first download the zip file for version 0.25 and unzip it somewhere on your home computer. Then SSH to the iPhone and use it to copy the folder you unzipped (Garf.app) into the /Applications directory on your iPhone.
You should make sure the permissions are set so that it can be
executed...your SSH program will most likely be able to do this. If it asks for a number, enter 755. If it gives you a grid
consisting of the Read, Write, and Execute, then make sure at least all
of the reads and all of the executes are selected.
The permissions should be set on both the folder (Garf.app) and the executable file inside the folder (garf).
