Phonestore USA via eBay offers the refurbished Unlocked Samsung Galaxy S4 Active Android Smartphone in Blue (pictured) or Gray, model no. SGH-I537, for $259.99 with free shipping. That's $5 under our mention from two weeks ago and the lowest total price we've seen for this phone. (It's currently $160 below the lowest total price we could find for a new phone.) In addition to being able to survive in three feet of water for up to 30 minutes, it features a 5" 1920x1080 Gorilla Glass touchscreen, Snapdragon 1.9GHz quad-core processor, 2GB RAM, 16GB memory, 8-megapixel rear camera (with an "Aqua Mode" for underwater pictures), 2-megapixel front camera, 1080p video capture, GPS, Bluetooth 4.0, 802.11n wireless, and Google Android 4.2 OS (Jelly Bean).
A 30-day warranty applies, but it's unclear who backs it.
