okay so i got my 2nd generation ipod touch over a year ago, but i started having difficulties with my computer, so i asked my friend to sync my ipod for me. she has the new generation with the voice memos, search ipod thing, copy and paste and what not, so when it synced, it upgraded my ipod. i dont want to jailbreak it, i just hate the upgrade. how do i downgrade back to the firmware that came with the second generation ipod? also im having troubleshooting installed applications. does anyone know about that?
