I lost my recovery key
i lost my recovery key, but i still know my password for my apple id. I sold all my previous devices and have no access to them. I registered my iphone 5 with the same apple id and its all good. i wanted to manage my devices, but i am unable to because its asking for the recovery key, which i dont have. Can somebody help me out on how i can do this. Really need your help. Anyone.
iPhone 5, iOS 7.0.3
