my computer crashed. (relatively unrelated) then i rebooted my tethered itouch 3g after installing ultrasn0w through rock (having cydia problems). i tried running blackra1n on a PPC powerbook g4 running mac osx 10.4. nothing happened at all. i then tried on an intel macbook running 10.5. saw geohot picture, and then shut down again. got my computer working, ran blackra1n from windows xp. same result as on 10.5. rebooting through blackra1n has worked previously for me, and i have tried restarting apple mobile device services. is there any way i can fix this, or just get my ipod working (short of a restore)?
