Unlimited calling plans seem to be all the rage these days, with every carrier provision subscribers with "all you can speak" plans. Now even iPhone users will soon be able to gab all they want, and not pay dearly for it in the next billing cycle. According to Engadget, AT&T will be soon offer a special iPhone bundled unlimited calling plan for the low price of just $119.99 a month. Not a bad deal I suppose, if you spend ever waking hour of your day with a cell phone symbiotically attached to your face.
