I am having trouble with this on beta 6. Apple has removed the option to switch "activation lock" off under settings. It is now an automatic part of "Find My iPhone".
I am preparing my iPhone 4 for sale and I have switched off Find my iPhone, signed out from iCloud, resetting the phone while entering my password.
When it boots again it still asks for my password. It has been removed from Find my iPhone from iCloud, but the activation lock is still there.
I have restored the phone to iOS 6, but the problem remains. It can not be activated without my password.
How can I remove it? I can not see how, I think I have done everything there is to try...
Is it a bug in iOS 6? Problems with Apple's servers? Will it not be possible to remove it before iOS 7 goes official?
Right now my phone is "unsellable"...
