I would like to undo the iLiberty installation for the moment, as I'm not using any applications, but I don't know how.

So you want it back to a stock 4.6 out of the box phone?

Install BootNeuter, set it as follows

4.6 Bootloader
Neuter Off
Fakeblank Off
Unlock Off

And press the flash button in the top right hand corner. Make sure that you have auto-lock set to never in the general settings of the iPhone

DO NOT interrupt the flashing process with ANYTHING. it would be better to turn airplane mode on so NOTHING comes in when you flash it

Then restore using iTunes to 1.1.4

I don't have an iPhone, but an iPod Touch (8GB)! Does that matter?

Use iLiberty+ then and using the Other Tools tab, boot the device into DFU mode and restore to whatever firmware version you have currently
