newegg offers the refurbished no-contract Apple iPhone 4S 16GB Smartphone for AT&T in Black (pictured), model no. MC918LL/A, or White, model no. MC920LL/A, for $479.99 with free shipping. That's $90 under the lowest total price we could find for a new unit, although we saw a refurb for $24 less in March. It's powered by the Apple A5 dual-core processor and features an 8-megapixel camera which is capable of recording 1080p video at 30 fps with image stabilization, dual-antenna system for faster downloads and improved call quality on GSM networks, AirPlay Mirroring, Siri voice-activated assistant, 8-hour battery life, and more.

A 90-day warranty applies, but it's not clear who backs it.
