With activation of new voice and data plans, AT&T Wireless offers the refurbished Apple iPhone 3GS 8GB Smartphone for AT&T Wireless in Black for 1 cent. (Search for “iPhone cosmetic” to find it.) With free shipping, that’s tied with our March mention as the least expensive iPhones we’ve seen in over a year. Sales tax is added where applicable. It features compatibility with AT&T’s 3G network, built-in GPS navigation with Google Maps, enhanced enterprise support, a 3.5″ touchscreen, at least five hours of talk time, and more.

Note: This item has “cosmetic blemishes.” A 90-day warranty applies, although it’s unclear who supports it. Also, there’s a $36 activation fee.
