I'll be headed to Europe for 7 weeks this summer. Most of the time we'll be in Italy, but we're also going to Paris, Prague, Vienna, and Greece. Our current mobile won't work in Europe, but I'm otherwise happy with the service and don't want to change, so.. I was wondering if there was a way to buy a european mobile, just for the two months we'll be there. Obviously we won't want a lengthy contract; just a phone that we can use to make local calls, arrange reservations, and so on. Any recommendations on a good cheap service that will work all over Europe that I can order from the U.S. before I leave? Also, I realize I'll need to get a universal power adapter for my iBook, but are there any other computer-related suggestions for our visit? Any and all wisdom from travelers and / or residents will be greatly appreciated!
