I will try to answer back to most of you.
Thank you for my warm welcome. My profile is for real. I am actually Tom Elliott, but I am 76 years old, not 78. I am male, not female. I may have entered the wrong sex in my profile. How do I correct my profile?
Yes, I talked to Apple store who gave me the warning that I need more than just one Apple ID. I have called the Apple store some time ago asking for some help. I don't remember the exact nature of my call, but the weird advice from Apple saying that I need more than just my Apple ID left me puzzled for a long time until I decided to ask iPhone forums for specific help.
Otherwise, you have answered my real question on Apple ID. So I will continue to use the same Apple ID for my three Apple devices. Thanks!
