Skype could be great! Unfortunately for Canada at the moment we have this thing called CRTC (Canadian Radio-television and Telecommunications Commission) which in short "protects" related Canadian business monopolies from non-Canadian competition.
I rarely use my iPhone held up to my ear. Almost always use it with a headset. It's only if I get caught without my headset handy and need to take the call that I use it like a "normal" phone.
