Does anyone know what the impact of 4g will have on existing technology, i.e. will 3g devices become obsolete like VHS recorders, or will we have a two tier infrastructure? Will 3g deals become cheaper? What impact has this had in other parts of the world where 4g already exists? I'm looking to get a new contract for my wife, but I don't want to sign up for another 3g handset for two years if its going to be useless within a few months......
