'Excellent network'?!

I have to question your assertion that 3's network is excellent and 'covers most of the country'. It's not particularly great - 3G is still some way off its touted broadband speeds - and 3's coverage is pretty patchy outside urban centres.

Notwithstanding that, a very interesting article, and one wonders what the implications might be for Apple/ O2's 'free Wifi, but you have to pay £35 a month for the tariff' idea.
