Which Dragon founded the technology retailer Phones 4u?

John Caudwell founded the technology retailer Phones 4u.

Caudwell established Phones 4u as a mobile-phone retailer and built it into a major business during the rapid expansion of the UK mobile-phone market. The company sold mobile handsets and contracts through shops and other retail channels.

The business became particularly prominent as mobile phones changed from specialist communication devices into everyday consumer products. Retailers such as Phones 4u helped customers compare networks, handsets and tariffs at a time when the market was developing quickly.

John Caudwell appeared as a Dragon on the British programme, but his time on the panel is separate from his business history. He is sometimes confused with Peter Jones, another Dragon strongly associated with phones and technology. The specific company clue identifies Caudwell: Phones 4u was the business that made him a well-known British telecommunications entrepreneur.
