    This is more a confirmation than me having an actual problem. Anyway, I just updated my 3gs to iOS4 GMC and I'm wondering whether switching off cellular data over wifi will prevent my iphone from looking for a data network even if I take the phone off airplane mode. I'm about to spend a week in Japan touring with my family and we require a phone to use while there. However, I don't wanna pay $100+ due to my phone sending data coz I need keep my phone on during our vacation.

    In short, the question is whether I will be able to use my iPhone in Japan without having to pay tons of $ in data fees after switching off all cellular data.

    If Data Roaming is set to off, your iPhone will not connect to any data service abroad. I was just in Europe, and my phone was on all the time, there was just no data. If I went to open email or the like, it would tell me to turn Data Roaming on first. No data charges! I could still connect to Wi-Fi just fine.
