Q: When I plug headphones into my iPhone 5, the home button will not work.  It switches functions to the button on the headphones only.  Is that normal with the latest ios version?  I just updated a brand new replacement phone.

I picked up a replacement phone today. After restoring the new iPhone from an iTunes backup, I noticed that the new phone doesn't let me use the front "Home" button on the phone if the iPhone 5 headphones are plugged into it.  When plugged in the headphone button becomes the only "Home" button.  I don't remember it that way on the iPhone 5 I just had.  Is this the functioality I should be expecting?
