International iPhone playboys, take notice: AT&T has announced flat-rate data plans for international traveling. We’ve heard a few horror stories of iPhone users being taken to the ringer by AT&T for international roaming rates, sometimes without even turning their iPhones on. If you’re a globetrotter, you’ll want one of the plans, which start at $25 for 20MB. You’re going to want the $60/50MB plan. It’s good enough to cover your ass, but you’ll want to use the Wi-Fi whenever you can.
