Um... I dont noe about u guys but i was able to downgrade from 1.1.3 to 1.1.1 quite easily. the way is to first have an ipod touch with the firmware 1.1.3. then on itunes, u option click restore. once u do that. u pick the file which contains the firmware 1.1.2. btw, u have to download the files for the firmware.

make sure u download 1.1.1 and 1.1.2 to ur computer. then after the restore is finished, option click restore again. then choose the file 1.1.1. once that is finished ur ipod will be a 1.1.1 ipod touch. after that install the apps for jailbreaking.
however, i do not noe wat to do to update back to 1.1.2.
i restored my ipod touch all the way to 1.1.1. i installed the apps for jailbreaking and then when i option clicked update, the ipod was not just updated, it was instead restored to factory settings and all the apps i installed for jailbreaking i.e. installer, it was erased. i need help on that part. try my way and tell me if u find out sumtin new.
