Internet. Seriously. Skype for the iPhone is the stuff dreams are made of. Prior to now, I'd been paying AT&T $3.99 a month for the pleasure of calling my parents in Singapore on my phone---and then 14 cents a minute per call. This meant that I tried to keep the iPhone-made calls to emergencies only---you know, like that time my brother Tom was held at immigration for trying to enter the United States illegally---and used Skype for the rest of them.
