I thought I read something here of a way to reduce iPhone data roaming costs, but couldn't find it. What I've read says that you don't want to do it, or to get a local SIM card, but that's not a great option to connect to our exchange server back in Auckland. If I'm travelling I really want to get my email and use my apps.
I don't have an iPhone but have been told that the company won't buy them because of the outrageous roaming costs.
