today I received two emails from apple stating updates to my apple ID account. One was downloading an app (resume builder pro) to a device not previously associated with my account. The other email said info such as billing address, phone number and password updated. I logged into my account and password was still the same (I have now changed it) billing address and email address were all fine. But under daytime phone there was a strange number listed 3496860780. (my real phone number was still listed under mobile) a google search revealed 349 is not a valid area code. What could this be? I have sold 3 iPhone 6's recently, could one of those still be associated with my account? Thanks in advance.
