This noon, my iPhone suddenly showed 'Activation Required'. I'm on iOS 6 beta 1 legit. However, I cannot activate my phone, it says that "Your iPhone could not be activated because the activation server is temporarily unavailable. I tried connecting it to iTunes, says the software has expired and must be outdated. But when I try to update it, I get: "iTunes could not back up the phone [blah] because a session could not be started by the iPhone" My iPhone 4 is brought outright, it is out of warranty. I'm a registered apple developer, only have 2 udids, my iPhone and my iPad. How to I activate / update my phone?
