I am looking to acquire two original iPod touches to install iOS 1.1 and iOS 2.0 on. I would like to have these running the old OS to simply have as reference. I have the OS downloads needed - is there anything I need to do in order to install the OS? Will Apple try to reject me from installing this? I know with iPhones going back to old version can be tricky. Any suggestions on installing old operating systems on the original iPod touch?
