I'll be traveling through The Netherlands, Germany and Belgium here in a few weeks and I wondered what I should know about my iPhone. I need to shut off data roaming? Do I need to call AT&T and tell them to enable international calls or anything like that? Is there a better option with an unlocked iPhone and buying a local SIM card there and shoving it in making it a local phone? Something I could use for maps or finding a restaurant maybe? That'd be the biggest use I'd guess. Checking email would be a nice bit as well. Calls (both back to the US and to local pals) would be a very distant third.
