Samsung today announced that Best Buy will offer a version of the Nexus S that is compatible with AT&T's network on July 24, with a pre-sale starting today. The Nexus S runs stock Android 2.3 Gingerbread, has a 4-inch Super AMOLED display, a 5-megapixel camera with video capture, 3D gaming support, and support for NFC (near-field communications) for tap-and-go mobile payments. The Nexus S costs $99.99 at Best Buy stores with a new agreement. It does not appear that AT&T itself will sell the Nexus S, giving Best Buy an exclusive. The FCC first approved the AT&T-compatible version of the Nexus S in February.
