If I travel internationally, can I use a SIM card provided by Sprint in a non-Sprint phone? I have a Cingular-branded unlocked quad-band GSM phone that I've used successfully in Europe with an Italian SIM card. I'm wondering if my new Sprint SIM card will work in there so I don't have to buy one of Sprint's GSM phones. They say they "cannot guarantee" that it will work, but I feel like there should be no problem if I know the phone has worked in Europe before. Does anyone have any experience doing this? Has it worked?

Thanks!
