I installed an app that I cant uninstall now, what is the easiest way to restore a jailbroken 1.1.3 to basically the state it was in before I installed any apps?

you should hold the sleep and home buttons together until the slide to turn off comes on, when it does carry on holding when the apple logo comes up let go of sleep but carry on holding the home button, this will put you ipod into recovery mode, then plug it in to itunes and restore back to 1.1.1, download the 1.1.1 firmware from the internet, then shift click restore and choose 1.1.1, then start the jailbreaking process again.

You can install bsd subsystem, then openssh. Then open ure windows pc and download and install winscp. Log onto the ipod touch with its wifi ip address and the user root and pass alpine. Locate the applications folder and look for "thenameoftheuninstallableapp.app" and delete that folder.
