Glyde offers the refurbished Unlocked Apple iPhone 5 16GB GSM Smartphone in White for $99.96 with free shipping. That's tied with our mention from Cyber Monday week as the lowest total price we've seen for an unlocked GSM iPhone 5. (It's the best deal today for a refurb by $10.)
Note: No warranty information is provided. The phone is fully functional but may show signs of cosmetic wear.
