I have a cellphone (iPhone on AT&T) that will cost $0.20 per minute (perhaps more) to make a call from the United States to Canada. I'm a cheap bastard and would like to avoid this charge whilst still using my cellphone to place the call. What options are available for me to do this more cheaply? Would I buy and use a calling card (and are there issues I need to worry about with this option), or are there apps that I can run on iOS through which I can call another country more cheaply than through AT&T?
As has been done with previous similar contests, has anyone posted a regression that estimates when Apple will hit the 1B mark on their recent app download contest? (I'm not talking about when Apple's web JS counter is programmed to flip early tomorrow morning.)
