ok last night i just jailbroke my 8gb itouch with the 2.0 firmware using winpwn. i also have windows. 1) all it seemed to really add was cydia, and i was wondering once you install something is there a way to delete it? and 2) on my itunes when i plug my itouch in it says there is a new firmware availble for update 2.0.1... is it safe to update even tho its jailbroken? im sorry if these questions sound dumb or easy to answer... im new to the whole hacking thing.
