My girlfriend is spending a semester abroad in London, and I'm looking for a cheap way to call her. The university provided her with a phone that receives calls for free. I'd like to figure out a way to call her for cheap. I'm assuming US Cellular is going to dish out some butt hurt on me if i use my cell, so what are my other options? Skype is the obvious...does anyone have details or advice? Something else? Also, what are these skype phones everyone is talking about?
