3G iPhone speeds

I've been amazed at how much I've come to rely on Internet access while commuting. Long gone are the days of reading a book on a train - I expect to be able to work or play via the web at all times.

The iPhone has much to answer for. It wasn't long ago that I took pride in getting my laptop out on the train and watching a DVD either to or from work. But that's so passé these days - if I can't do it on my iPhone then it can't be done.

However, the iPhone and other smartphone handsets wouldn't be as attractive without the network behind it. The mere fact that I can sit on a train, use a touch-screen device to write a blog post and know that once I click 'publish' the network will just take care of it is incredible.

O2, Vodafone, and all carriers advancing their networks should be commended since they bring the connectivity we desire to the handsets we love.
