The good news about the second generation iPhone 3G is not so much the technical improvements as the fact that better usage options are now available to would-be owners. For example, there will be a pay-as-you-go option in the UK. Admittedly the initial cost of the iPhone is steep but as an infrequent user of cell phone technology I will probably save a fortune over an expensive long term contract.
So, along with 300,000 others I have registered my interest. I did that last time, but I am a whole lot more serious this time!
Of course, O2 may still scupper my plans by insisting that I have a bank account that suits them and not me!
