Samsung on Tuesday unveiled its second folding phone, a "Z Flip" model with a lofty price tag aimed at "trendsetters." The Galaxy Z Flip will be available beginning Friday, Valentine's Day, at a starting price of $1,380, said head of Samsung product marketing in Rebecca Hirst said at a San Francisco unveiling. "It changes everything -- space, size, and the very way we use it," Hirst said as she held a Z Flip in the palm of a hand. "The Z Flip is a statement smartphone; it is for trendsetters and trailblazers." gc/rl
