The iPhone X will cost $999. But there are some people who have held onto their original version — with good reason. It could cost you 10 times the price of the iPhone X, which Apple AAPL, +3.37% unveiled Tuesday. Some first edition iPhones are more valuable than others. Bob Kraft, a retired business owner in Madison, Wisc., received an offer of $11,000 for an unopened iPhone that came in a factory gift box from Apple with a red ribbon — and he turned it down. His asking price was $15,000. “That was tempting,” he says. “But I’m not in a hurry to sell it.” He’s one of at least a dozen sellers of the 2007 iPhone who is hoping to make hay from the 10th anniversary of the iconic smartphone. He has discounted the phone from $18,000, the price he first listed it for on eBay about five months ago. He’s hoping a collector will see value in the original. “If you open it, it’s only worth a couple of bucks.”via
