I'm on Vodafone and have been for 15 years or so, so I do understand that there may be some "customer loyalty" to one network or another. However, and this is probably me failing to understand something fundamental so I'd welcome some explanation, I don't really understand the apparent rush to unlock the iPhone from O2 in the UK. It seems to me that the deal with The Cloud, and from July 11th, BT Openzone make the O2 contracts quite attractive. What am I missing? Is O2 coverage much worse than any of the other networks? Do the other networks have comparable WiFi deals?
