i was told i could get 8.0 free by downloading and doing all these steps so i did and had iOS 8 for a few minutes untill my phone resetted and said "Activation error, this device is not registered as part of the iPhone Developer program" and i tried to go to iTunes to restore my phone and it said the same activation error... i don't know what a 'Udid' is or how to get one but i cant access my phone or itunes to reset it.. thanks
