Nexus S from Samsung. Here's the rundown: 4-inch WVGA display, triband HSPA with AWS support (no HSPA+, seemingly), 5 megapixel camera, NFC, 16GB of onboard storage, 512MB of RAM, available on T-Mobile. It's also got a gyroscope -- as do the existing Galaxy S phones -- along with something being called the "contour display" (which matches up with rumors we've heard), integrated VoIP support, and Android 2.3 Gingerbread. Interestingly, the phone's quoted as having nothing more than a 1GHz Cortex A8-based Hummingbird processor, seemingly shooting down rumors that this thing would be rocking the Orion dual-core setup. Ah, well! Peep all the shots in the gallery below.
Update: And now it's official! According to the Official Google Blog, the Nexus S will be available for purchase after December 16th "online and in-store from all Best Buy and Best Buy Mobile stores," either unlocked or with a T-Mobile plan. Across the pond, look for the Nexus S to hit December 20th at Carphone Warehouse and Best Buy UK. Videos after the break.
Update 2: Best Buy's let out the pricing details: $199 with a two-year T-Mobile contract or $529 unlocked. Also, be sure to check out our rundown of the Android 2.3 SDK!
