I had to change my password for the app store today. Had no problem changing it, but after I changed it, I received a message on my Mac that said Do you want to add =1 [my phone number] to i Message? This phone number was associated with the Apple ID [my Apple ID] on HunnieBunnie's iPhone. I do not know whether to say yes or no. I do recall ever seeing this message before. Perhaps it is something new to do with OS 10.3.3. Advice appreciated. Thank you!
