This week's edition of The Fonecast starts with an Olympic theme.

We talk about mobile phone coverage at the London 2012 games - and then move on to mobile payments for Olympic visitors.

Three UK is changing the way it blocks age-sensitive content accessed via its mobile network.

Previously it's followed a similar policy to the UK’s other major networks, filtering websites to protect users who may be under 18. Commercial web content that would be classified as '18+' in other formats (e.g. magazines, films and games) has been restricted until the customer provides proof they're at least 18 years old.

In recent days Jean-Marie Messier has been hitting the headlines again.
