I just got my first iphone, iphone 5c. I have an ipad2 and has been in service about 2 years. After setting up the iphone 5c (w/icloud), my ipad now is requiring me to have a passcode lock set. I didnt have a passcode lock set prior to setting up the 5C, which I did set a passcode lock for. Any reason why this happened, and how to remove the passcode requirement from the 5C?
