Yes Gareth, I did mean that you should find the number and note it down. If everyone did it then there would be no use in stealing them (I was thinking particularly of the consequences of phones being stolen from children).
Bill .. I assumed that, as many phone manufacturers are international, the same trick would work wherever you lived.
Dave the paper said 17 numbers .. I never bothered to count them but presumably 15 will work just as well
