To me any new handset promising so much from the 'internet' needs to be 3G for an European launch. I'm sure Wi-fi is everywhere but the perception by the public is 3G the de-facto standard today. The operators spent so much time and money ramming 3G video calls and data down our throats it would look to be a u-turn on all that. That said I wouldn't be surprised if they insisted wi-fi is disabled>!? Operators will become pipes - utilities like water, gas and electricity but with data.
I wonder if Vodafone will mess up the mobile transcoding with iPhone like they did last month with WAP, is it mobile or is it web?
