Nexus S Smartphone, Best Buy

Visit Best Buy Mobile's online or offline stores to place your order.

The slab-style smartphone ships with Android 2.3, aka Gingerbread, and features a 4-inch Super AMOLED screen, 1-GHz processor for showing 3D graphics, VGA front-facing and 5-megapixel rear-facing cameras, and support for near-field communication (NFC). And being a "pure" Android experience, it also features the most up-to-date Google mobile apps, including Google Voice.

Best Buy Mobile is offering free Nexus S phones with the activation of a two-year contract on AT&T, Sprint, or T-Mobile. But act fast—the deal lasts until 1pm Eastern on Wednesday.

PCMag gave the Nexus S 4G different ratings based on the carrier. We gave the $99 Sprint version three out of five stars for "noticeably slower" 4G download speeds, though last week Sprint said it would begin updating the devices to fix these known problems.

Meanwhile PCMag gave the $199.99 Nexus S on T-Mobile four out of five stars ("average consumers can find even-better high-end smartphones," mobile analyst Sascha Segan said).

AT&T only recently began offering the Samsung-manufactured "pure Android experience" for $99 with a two-year contract.

Google launched the Samsung-made Nexus S last December. An unlocked version earned high praise from PCMag columnist John Dvorak. Click on the slideshow below for more angles.
