I have been frequently traveling to Mexico and Europe and even with my unlocked old EDGE iPhone the local data services are way too expensive in comparison to what I paid in the USA.
Therefore there is no need to pay for data usage in another country unless you really save money on it.
I do use wi-fi in the company where I worked and in the hotels where I stayed.
I do love my iPhone and so far I think I will never replaced it with a blackberry.
Anyways the business crackberries are always used to pay those exotic data roaming charges, and if they don't care nowadays they will not in the future.
