I just bought the iPhone 4 a few days ago and I love it! It's the best phone there ever is and was. But my concern isn't with the iPhone itself but rather how I'll be able to use it abroad. If I'm planning on traveling quite extensively over the next few months, I'll be roaming A LOT! But again, I'd like to keep in touch with family at least via email or IM (hopefully Skype over WiFi etc.). How will go about getting a global data plan? I know AT&T offers some minimal package for an insane amount of money, but is there something that isn't so widespread that somebody would know of? I'm not AT&T (I live in Croatia), so the AT&T thing wouldn't work for me and the international packages the local carriers offer are so pricey that I won't even consider them. Any suggestion is appreciated. Thanks!
