I keep talking about taking my iPhone to Israel.

On one hand, I want to be able to check emails throughout the day when I am roaming the streets and doing tourist-like things. On the other hand, I don't want to be hit with a huge bill when I get home. Since AT&T has yet to support an international plan designed for Israel and the iPhone (they have for the Treo and Israel), I don't plan on making calls from my phone or using data.

But what about the wifi option? Can I get away with using just that?

The iPhone Tips for International Roamers describes how you can use Wifi to get data on your iPhone while traveling internationally. But what scares me is the language is not very encouraging...

When I go ahead and look at Keep Data Roaming "OFF" section under Settings > General > Network > Data Roaming, it reads:

When abroad, turning off data roaming may avoid roaming charges when using email, web browsing, and other data services.

The word "may" is what concerns me. Here is a picture:

If I was in Israel today, I bet I would follow the instructions, and try to just use Wifi only and make sure the data roaming is off. But I know I would check my AT&T account the day after to see if I was being billed.
