Guarantee Cellular via eBay offers the refurbished Unlocked Apple iPhone 5 16GB GSM Smartphone in Black or White for $89.95 with free shipping. That's tied with our mention from three weeks ago and the lowest price we've seen for an unlocked GSM iPhone 5. (It's the best deal now on a refurb by $6.)

A 60-day warranty applies, although it's unclear who provides it.
