Smartphones of Mobile World Congress 2011

Despite the Nokia and Microsoft headlines at the start of the show, this year's Mobile World Congress was definitely dominated by Android. Most of the 15 or so smartphones that were announced in Barcelona, Spain, sported either 2.2 Froyo or 2.3 Gingerbread, which is music to our ears. Here's a list of all of the smartphones that were announced at Mobile World Congress 2011.

LG Optimus 3D: Yes, it's 3D on a phone! Though we're not sure if it's for everyone, it's certainly an impressive leap in the mobile space.

Samsung Galaxy S II: Samsung continues its Galaxy S series with the superfast and shiny Samsung Galaxy S II.

Sony Ericsson Xperia Play: Sure we had our misgivings about its Super Bowl ad, but the Xperia Play does look like a decent phone. But will it be the true "PlayStation Phone" that people might be expecting? We'll see.

Sony Ericsson Xperia Neo: Sony Ericsson released other smartphones too, like the Neo with the 3.7-inch touch screen.

Sony Ericsson Xperia Pro: This is the Neo with a slide-out keyboard.

ZTE Skate: ZTE releases its first "jumbo phone" with a 4.3-inch display, but it only has an 800MHz processor and a 5-megapixel camera.

ZTE Amigo: ZTE also announced a couple of other Android phones. The Amigo has a slide-out keyboard and a 3.2-megapixel camera.

ZTE Blade: The ZTE Blade does not have a keyboard, but just a 3.5-inch touch screen. It does run Android 2.1, but ZTE promises it is upgradable to 2.2.

Huawei Ideos X3: Huawei gets in on the Android action, too, with the Ideos X3, which promises to run on 2.3 Gingerbread.

HTC Incredible S: The HTC Incredible S gets an update with the HTC Sense interface. It also has an 8-megapixel camera on the back plus a front-facing camera.

HTC Wildfire S: The Wildfire S gets HTC Sense too, though it only has a 5-megapixel camera.

HTC Desire S: You guessed it, the HTC Desire S gets the Sense UI as well. It has a body similar to the HTC Legend and has a 1Ghz Snapdragon processor.

HTC ChaCha: One of two "Facebook phones" that were announced in Barcelona. The ChaCha has a full QWERTY keyboard.

HTC Salsa: The HTC Salsa is the other so-called Facebook phone, but it has no keyboard. It does have a 3.4-inch touch screen.
