newegg offers the refurbished, no-contract Apple iPhone 4S 16GB Smartphone for AT&T in White, model no. MC920LL/A, for $489.99 with free shipping. That's tied with our mention of the black version from three weeks ago as the best price we've seen for a no-contract iPhone 4S. 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.
