I will be in the D.R. for about a month and I can use my iPhone for calls to U.S. numbers but AT&T told me I will be billed for $1.50/min with the international plan ($6/month). I understand that the cell service down here is Claro and I could get a prepaid phone with them for local calls. I was wondering if anyone has any experience using the iPhone down here. I am using AIM and Skype to iChat my family and friends back home but it would be nice to use my phone more since I will be out of my hotel room a lot. Thanks!
