Currently have a JB iPad2 5.01, and use it for a lot of work out in the field (Commercial Real Estate). Would really benefit from a 4G connection and thinking of upgrading to the new iPad once it's released and giving my iPad 2 to my dad (since my mom has commandeered the iPad 1 we got him for Xmas) to use on their iTunes account.
My question is can I switch the iTunes account on the JB iPad2 over to their iTunes account simply by plugging in it to their iTunes and having and having iTunes make the switch, preserving the JB? I understand that it would lose the media saved on it (it's my movies and music, not something he would be interested in anyway). Or would it need to go through a restore, in which case that will be forced to go to 5.1 and no jailbreak until one was released.
