As nobody could help me with how to fix the problem that redsn0w and pwnagetool crashes, i decided to go on a windows xp and try to jailbreak my first generation iphone there (it's currently on 2.0.1).
I did everything as asked, redsn0w did everything fine except for the last bit.
My iphone gets stuck saying 'downloading jailbreak data' and after ten or more minutes, it restarts and gets to the emergency call screen...
what's the problem?
please help me!!
