COVENTRY, England, Dec. 30 (UPI) -- A British mother said she was shocked when an iPhone 4S at a Tesco store told her 12-year-old son to "shut up" with a four-letter profanity.
Kim Le Quesne said her son was testing out the phone's Siri system, which answers spoken questions, at the Tesco store in Coventry, England, and it gave him the obscene answer when he asked it to tell him the number of people in the world, The Sun reported Friday.
"The phone was a demo version and was low enough on the shelf for Charlie to have a go with it. He asked it a simple question and we couldn't believe the filth it came out with," the mother said. "I thought I must be hearing things. So we asked again and the same four-letter stuff blared out. I asked for the manager and after staff heard it they agreed to unplug it."
Workers at the store said pranksters had tampered with the set-up instructions for the device.
"We have launched an investigation. The handset will be going back to Apple for diagnostic tests," the store said in a statement.
