MWC is always a hotbed of new products ranging from hardware and components to handsets and accessories for mobile phones. This year a bunch of accessories have been seen including the latest Bluetooth headset from Novero that is aimed at men.

The headset is called the Lexington and has an understated black with brushed steel design. The device has a stainless steel clip to connect it to a shirt pocket when not in use. Novero ships the Lexington with a charging carry case.

The tablet market is going to be hot this year with a glut of new tablets coming to fight the iPad. Many of the tablets will be appealing to users looking for a computer and an eReader since they can be used as both. The OpenTablet 7 device was unveiled at MWC today.

The tablet has a 7-inch multi touch TFT LCD with LED backlighting. The tablet also offers WiFi, Bluetooth, cellular connectivity, HDMI output, and dual cameras for taking still shots and HD video. The tablet also has a microSD card slot for storage and a USB port.

Huawei has introduced its 7-inch Android Tablet prototype at Mobile World Congress 2010. The device supports information-sharing across screens to present the same content at the same time on computers, cell phones and TV screens.

The SmaKit S7 tablet also allows you to easily access local information, visit social networking websites and shop from online application stores. It can be connected to a home gateway, TV or Android handsets to provide an integrated home solution. Some other features include a 7 inch wide touchscreen with a resolution of 800 x 480 with a customized Android user interface and special customized home screens.

Remember the iKey AK-39 military-grade wrist keyboard? It was a small keyboard made for a soldier to wear on his or her wrist in order to manipulate a rugged, portable computer.

Now iKey has a new keypad, and it’s an OEM product meant to integrate directly with wrist-worn computers. The 17-key keypad “functions just like a cellular phone does when texting”. It also sports an integrated pointing device, dedicated mouse-click button, and an Enter key.

From the fine folks at Pong Research(They haven’t done much since testing Pong consoles in the late seventies apparently) come these anti-radiation cases for the iPhone 3G, iPhone 3GS and Blackberry Curve… Despite the fact that radiation from cellphones has not yet been proven to harm people.

The Pong anti-radiation cases are mostly made of silicone, with a “Pong gold PCB module” embedded in the case. Apparently the module has been proven to reduce the radiation from an iPhone into a user’s head to “a third of what it would be without the case.”

Just when you think you’ve seen it all, you see some guy lighting a smoke with his phone. We showed you one like this last year, but we weren’t sure if it was real or not. This one’s called the Machismo, because obviously its made for manly men.

Just slide open the safety hatch in back and a few seconds later you have a freshly-lit cigarette. $69 gets you these specs: Tri-band GSM phone, Dual SIM slots, 2.5-inch touchscreen, 1.3-megapixel camera, Multimedia playback and likely a burnt finger or two.

Pantech just dropped their latest cell phone, the Sky IM-U560K. This one is designed for girls and packs in a touchscreen display and an accelerometer for games and applications. It also comes in handy for manipulating the GUI using hand gestures and movements.

The Sky IM-U560K has a 2.6-inch screen, a DMB TV tuner, MP3 player, and a Korean to English Text to Speech Translator. Nothing on pricing yet, but we’ll let you girls know when we know.

Toshiba’s ZX900 Cell TV claims to have 143 times the processing power over existing televisions. That processing allows for Toshiba’s Resolution+ upscaling, a 480Hz frame rate and some home media server capabilities. Net TV applications include Netflix, VUDU, CinemaNow and Pandora, along with 802.11n WiFi and 1TB of HDD for streaming and storage.

It also boasts video phone capability, but it’s we aren’t sure if it has a built-in webcam or if you bring your own USB. The Japanese version has eight tuners, but that has been removed from this US version. These displays use KIRA2 LED-backlit displays with 512 zones of localized dimming, as well as built-in Wireless HD.

Frontier has unveiled its new 10-inch Pine Trail netbook, the Frontier UX netbook. This netbook comes with a DVD drive, so you can watch your favorite DVD movies wherever you are. It also features a 6-cell battery, which will give you up to 6.4 hours of power.

The Frontier UX weighs about 2.9 pounds and is powered by a 1.66GHz Intel Atom Pine Trail N450 processor, has a 1024 x 600 pixel display, 2GB of RAM, a 320GB hard drive, 802.11b/g/ WiFi, and Microsoft Windows 7 Home Premium.

I can certainly see the desire to have noise-cancelling earphones with kids around. I can’t work if my son and his friends are playing games in the living room, they are too loud. A nice set of headphones would help me put up with his goofy friends and all their giggling.

Audio-Technica has announced a new set of headphones called the ATH-ANC1 QuietPoint active noise-cancelling on-ear headphones. The product name is long enough and they will sell for $129.95 in January.

The Chevy Volt electro-carriage will roll out for drivers next year, and when it does it’ll be iPhone and BlackBerry friendly. The image above was shown off at the L.A. Auto Show, revealing a BlackBerry displaying the Chevy Volt’s battery charge status.

The iPhone and Blackberry apps will start off with the ability to control when the Chevy Volt gets charged. The Volt will alert your cellphone when it’s fully charged. Chevy also hinted that other cellphone platforms will be compatible with the Volt eventually as well.

You nicely dressed dudes in your fancy cars have to stay connected at all times right? Even when diving? The underwater cellphone should come in handy then. It comes with a built-in speaker and microphone on the Neptune Space full face mask.

You also get a 40-meter cable which can be modified to accommodate just about any request. A quick release waterproof rubber connection lets the diver separate from the cable anytime they want.

One of the things that has many iPhone users angered is that while the iPhone has tethering capability, AT&T has blocked the feature. I can only imagine how angry the users would be if they had been able to tether the iPhone for years and the feature was cancelled without notice. Sprint has done just that for some of its customers.

A poster going by kevinapg has posted at the Sprint Blogs that the ability to tether his Blackberry handset has been blocked. The poster states that for years tethering has been supported through the Sprint Smartview software.

I haven’t used a home phone line in years other than for DSL. I make and receive all the calls I get on my mobile phone. If you still use your landline for placing and receiving calls and you want to get the contacts list from your mobile onto the home phone VTech has the product for you.

VTech has announced the first home phone called the DS6321-3 that sells for $99.95. The handset can connect to your mobile phone via Bluetooth and download the contacts and phone numbers from your mobile to the landline.

Is it a camera or a phone? Samsung’s latest is a 3G cellphone in a 12 megapixel camera. Just as Darth Vader is more machine than man, this M8920 / SCH-W880 is more camera than phone. Certainly more camera than most 12 megapixel cameraphones are. It’s not official yet, but the announcement will come soon.

The most interesting aspects of this one are the extending 3x optical zoom and the dedicated camera controls like a mode dial, shutter and zoom, along with a 3.3-inch WVGA AMOLED display. Some other specs are HD (720p?) video, HSDPA data, WiFi, GPS, Bluetooth, microSD slot, and DMB mobile television.
