Dan is back. Hesse that is. Sprint (NYSE: S) Nextel’s CEO is going all Hollywood again as the public face of Sprint in a new ad that will begin airing during this Sunday’s Emmy Awards show, WSJ reports. Shortly after Hesse joined the struggling carrier nine months ago he appeared in an ad campaign last March to promote the Simply Everything plan that led to an industry-wide shift in flat-rate plans at the other carriers. This time he’s hawking ReadyNow, a new service Sprint launched that gives customers one-on-one time with a retail customer representative to get their cellphones setup with all their personal information and configured however they wish. “Truth is, technology’s only great when you know how to use it,” he says in the similar black-and-white commercial. “We want to help you get the most from these amazing devices. So come by a Sprint store for a personalized setup. You’ll walk out an expert.”
