Sky Dayton, founder and chairman of the phantasmagorical Helio, has announced that he's stepping down as CEO to become chairman of the board of the last-man-standing MVNO. Helio's new CEO will be Wonhee Sull, formerly the company's president and COO, and obviously a direct conduit to co-owner SK Telecom. "Helio has reached a point in its development where I feel the timing is right for this change... As we have for the past three years, the two of us will continue to define Helio's direction and future," said Dayton. Whether Sky's really ready to move on or not we'll never know, but it's certainly possible that the recent influx of cash (and increased ownership) from its Korean parents and dwindling marketshare of US MVNOs led SK to step in and get things on track.
