The web is buzzing with rumors and ideas on what Apple’s next big idea may be. Combine an opinion piece by TheNextWeb.com that Apple may be considering a FaceTime and iMessage-like audio messaging service and some news floated by MacRumors that Apple has just open-sourced its proprietary audio codec.

Put simply, the pieces are in place for high-quality, free phone calls on your iPhone.

Both articles are worth a read. What if Apple is not only the next Sony, but also the next AT&T?
