My son told me I could update to the new ios 6.1, but it ended up he updated to a beta that i'm not allowed to have. the activation process won't let me activate the phone due the fact that apple won't let me because i'm not a developer. Seeing as i don't want to pay $100 to use my phone i tried restoring it, but a full restore on itunes 11.7 renders a message saying that it cannot contact the update server and i should connect to wifi, but i am. however, restoring from a backup says it cannot start a session with my iphone. what to do? i've considered downgrading itunes, as i didnt have these error message on 11.6
