iPhone was released, our first reaction was: "It supports free calling over 3G, hooray!" That was, of course, followed quickly by: "It's only free until August, boo!" However, there's some slightly good news on that latter front, with free calling receiving something of a stay of execution. You can now stick it to the man until the end of 2010, at which point the whole "mobile subscription" thing comes into play. Why the delay, and what will you be paying for the privilege when the new decade really starts rolling? That we just don't know.
