Hi, Im trying to upgrade and JB the iPod Touch 2G of a friend but can't install the "official" last firmware for this model (4.2.1). iTunes downloads it but after that it says that my model isn't elegible for that IPSW... WTF? Is there any way to install it?, now it's downgraded to 2.1.1 because the other IPSWs gave me the same error on iTunes... This is very annoying, seriously. Any help will be highly appreciated. Thanks in advance, Daniel.
