'Who are you?' - Blair's first mobile phone message

Paris, January 12: It's not often that former British Prime Minister Tony Blair is not recognised. But his first foray into the world of mobile phone messaging left one friend puzzled.

Blair told a conference organised by France's ruling UMP party in Paris he got his first mobile phone six months ago.

"When I lived at Downing Street I never had one. I got my first mobile the day I left," said Blair, who is now a Middle East envoy.

"I sent an SMS (short message service) to a friend, but given my lack of technological knowledge I didn't realise the telephone hadn't identified me as the sender. I got an SMS back saying: 'But sorry, who are you?'", Blair said.
