Mobilepros1 via eBay offers the refurbished Unlocked Apple iPhone 5s 16GB Smartphone for GSM Networks in Gold, Silver, or Space Grey for $158.99 with free shipping. Although we saw it for $9 less last month, that's the second-best price we've seen for an unlocked iPhone 5s 16GB smartphone. (It's a current best for a refurb by $6.)
