Bought new iPhone 6s. Asking for different apple id. Why? My girlfriend's brother just ordered a new iPhone 6s and he tried setting up his phone but the store I believe keeps asking for a password for a Japanese registered email address. Assuming that's not meant to happen. Any reason this is happening? Is the phone refurbished or stolen and not new? Thanks for any info
It sounds like he has encountered Activation Lock. He can check that theory here:
