I'm getting an iPod sometime in the near future (I don't know if I'm gonna wait for the 4G or just get the 3GS). I'm going to Europe for a month (July-August) and I'm wondering, will I be able to use my phone without spending tons of money because of international rates? Do they offer any kind of temporary plan so I can still use voice and data without being charged by the minute/kb? I'll definitely need some kind of phone over there but I don't really know how international rates work.
