Thanks for the explanation SC, I am due an upgrade so that might be the solution!
DO'L, let he who is without sin, cast the first the first stone. Sometimes, as a woman travelling alone, it is not a clever idea to strike up conversations with strangers; that is a sad indictment on society and no reflection on my friendliness. I'm a country girl and fairly used to being able to talk to people. Secondly, I used one example of when I might want to use my mobile phone for surfing; there are others.
Cheers
