I bought a lovely shiny new iphone 4 on launch day from the Newcastle apple store, and I love it, I have not had any of the problems I have read about, until my home button started to become unresponsive, so I made a genius appointment and the although the problem did not show itself to him, he has arranged for me to go back tomorrow and swap mine for a new one, I just hope its as good as mine minus the home button problem, I just thought I would share my happy experience.
