Can I upgrade stock 1.1.4 iPod touch to 2.0 using this firmware: iPod1,1_2.0_5A347_Restore on latest iTunes (8.x)? I mean do I need to downgrade iTunes or smth? Please answer me as I do not wish to get another bricked iPod or smth. If upgrading it like that is not possible, please tell me what I need to do. Thank you!
