I was asked at CAK (small regional airport with ONE security machine/metal detector for all gates) to remove the batteries from my cell phone and put the phone & batteries through the xray separately. I politely declined and told the security person if she wanted to make a call to verify the phone, that was fine, but I wasn't about to reprogram 200+ names into the phone because they were worried it wasn't really a phone....
She let me put the battery cover & phone through separately (battery still in it's rightful place).
