Look out, Sprint -- if you aren't careful, you might just end up pulling a Palm. Shortly after Dan Schulman, Sprint's prepaid business honcho, announced that he'd be leaving The Now Network for a position at American Express, product development guru Kevin Packingham has announced that he'll be packing out on Monday. The 39-year old is responsible for spearheading some of Sprint's most highly sought after products, namely the HTC EVO 4G and Samsung Epic 4G. He'll be leaving his Senior VP office in order to "run another company in Kansas City," but Sprint's remaining mum on what exactly that company will be. For what it's worth, a spokeswoman for the carrier confessed to the Wall Street Journal that the departures aren't a concern, and that "Steve Elfman, president of Sprint's network operations and wholesale business, and Fared Adib, vice president of product development and Mr. Packingham's lieutenant, will share oversight of product development."
