Smarter.Phone via eBay offers the refurbished Unlocked Apple iPhone 6 Plus 64GB GSM / CDMA Smartphone in several colors for $194.99 with free shipping. That's $15 under our January mention of a GSM unlocked model, $364 off, and the lowest price we've seen for an unlocked unit. Note: A 3-month warranty applies, although it's unclear who backs it. It comes with a non-OEM charger.
