12-year-old Charlie Le Quesne was testing the iPhone 4S at a Tesco outlet in Coventry and asked it: "How many people are there in the world?"
Siri, which is a personal assistant that answers questions put to it, said: "Shut the f*** up, you ugly t***."
His mother, Kim Le Quesne, was with him and said she could not believe what it had said and asked the question again, only to get the same answer.
The manager and staff were called in, who unplugged the phone after hearing the swearing. They told her the glitch was due to someone tampering with the phone's set-up instructions.
The current assumption is that the rude phrase was stored in that handset as the name's of the phone's owner. This results in that name being repeated whenever a question was asked.
Tesco said: "We have launched an investigation. The handset will be going back to Apple for diagnostic tests."
