 Apple is the world's second-largest information technology company by revenue after Samsung Electronics and the world's third-largest mobile phone maker after Samsung and Nokia. Fortune magazine named Apple the most admired company in the United States in 2008, and in the world from 2008 to 2012. However, the company has received criticism for its contractors' labor practices, and for Apple's own environmental and business practices. 

The revolutionary App Store℠ offers more than 800,000 apps to iPhone, iPad and iPod touch® users, with more than 300,000 native iPad apps. App Store customers have downloaded over 40 billion apps, and Apple has paid over seven billion dollars to its incredible developer community. Customers can choose from apps in 23 categories, including newspapers and magazines offered in Newsstand, games, business, news, sports, health & fitness and travel.

 Windows Phone is a series of proprietary mobile operating systems developed by Microsoft, and is the successor to its Windows Mobile platform although incompatible with it. Unlike its predecessor, it is primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010, with a release in Asia following in early 2011. The latest release of Windows Phone is Windows Phone 8, which has been available to consumers since October 29, 2012. Microsoft also has a new version, Windows Phone Apollo Plus, in the works.  With Windows Phone, Microsoft created a new user interface, featuring its design language called the Modern design language. Additionally, the software is integrated with third party services and Microsoft services, and sets minimum requirements for the hardware on which it runs.

 The BlackBerry is a line of wireless handheld devices and services designed and marketed by Research in Motion Limited (RIM) operating as BlackBerry. The first BlackBerry device, an email pager, was released in 1999 the most recent BlackBerry devices, the Z10 and Q10, were announced on January 30, 2013. The user interface varies by model; most feature a physical QWERTY keyboard, while newer generations have relied on a multi-touch screen and virtual keyboard. A BlackBerry can shoot video, take photos, play music, and perform online functions such as web-browsing and emailing. They can also send and receive push email and instant messages while maintaining a high level of security through on-device message encryption, and are designed to function as personal digital assistants. BlackBerry devices support a large variety of instant messaging features, with the most popular being the proprietary BlackBerry Messenger service. The BlackBerry Playbook is a tablet computer offered by the company. The 100 millionth BlackBerry smartphone was shipped in June quarter of 2010 and the 200 millionth smartphone was shipped in September quarter of 2012.

 Samsung Galaxy S4

 The display of Samsung S4 is super fine and has a Full-HD AMOLED screen providing a resolution of 441ppi. Corning Gorilla Glass 3 enabled in the device provides good protection to the handset and makes it more vulnerable.

Processor: There is a 1.6GHz Exynos Octa-core chip or a 1.9GHz quad-core Qualcomm, depending on your region.

Battery: The 2600 mAh removable battery is of good quality with a standard with a standing and talk time.

Connectivity: The phone offers a remarkable connectivity to 4G LTE on all networks with LTE Roaming.

HTC One 

 Instead of just focusing on a higher megapixel count in your camera, HTC has gone for larger pixels on the CMOS sensor (about 4 square microns) instead of the 1.96 square micron pixels on the One X's 8-megapixel sensor). There's also optical image stabilization built-in, which should help with video taking.

Design-wise, the metal chassis is a nice return to the days of the HTC Sensation and the metal unibody builds of HTC's previous smartphones. We're fans of both the black and silver models and the handset feels nice in our hands. It also frames the 4.7-inch full-HD display nicely.

 4-inch Retina Display screen, at 1136 x 640 pixels. All previous iPhones had 3.5-inch screens. Like earlier Retina Displays, the screen offers 326 pixels per inch

The Apple A6 processor. The iPhone 5 is the first Apple device that uses this processor, which the company claims offers twice the performance of the A5 chip in the iPhone 4S

4G LTE networking support and support for DC-HSDPA networks

The Samsung Galaxy S3 is the company's flagship device of 2012. As one of the most anticipated devices of the year, this device is the first to come with a Exynos 4 Quad processor. It also has Android 4.0, a 4.8-inch 720p Super AMOLED display, 1 GB of RAM, and it is only 8.6 mm thick.

Samsung also went the extra mile by giving the device many features that will make your life easier. Picture taking, calling and sharing is smarter than ever with the Galaxy S3. This device is truly a beast 

 A 1.5 GHz quad-core Snapdragon chip powers a slew of on board radios, including LTE, WCDMA, Bluetooth 4.0, GPS and NFC. On board storage is limited to 16GB, but a microSD slot allows for up to 32GB of additional space. The NFC chip supports short-range wireless connection to a host of Sony devices, including all 2013 Sony TVs and a new line of headphones and speakers. The 13-megapixel camera is very fast and images captured appear quite clear, though we weren't able to view any photos on a larger display. Audio quality is crisp, as well.

Most impressive, however, is the 441 ppi display — this might be one of the most incredible screens we've ever seen on a mobile device. Colors are sharp and clear, video just about leaps of the screen… it’s really an impressive experience.

 Samsung unveils Galaxy Xcover 2

 Measuring in at 130.5 x 67.7 x 12 mm and weighing 148.5g, the Galaxy Xcover 2 is powered by a 1GHz dual-core processor with 1GB RAM and comes with 4GB of on-board storage with external expansion support up to 32GB.

It also sports a 5-megapixel rear camera, capable of capturing underwater images, and a VGA front snapper. A so-called Motion UI enables users to perform functions, such as muting the handset, with gestures.

The phone measures 5.875 inches tall and 3 inches wide. On the left, you have a flushed volume rocker that's situated quite low on the edge -- almost right in the middle of the body. I found myself often pressing the empty space between the rocker and the QuickMemo shortcut key (which sits right above it), when trying to turn up the sound. Up top are a 3.5mm headphone jack, and a small collapsible TV antenna on the right corner. On the right is a sleep/power button and at the very bottom is a Micro-USB port for charging. Also this phone has a 5.5 inch screen.

Nokia 808 Pureview 

 Remember that Nokia PureView tease from a few days ago? Well, suddenly it all makes sense. We are indeed looking at an imaging flagship phone and a true successor to the N8. Before we move on to its craziest feature -- the camera, of course! -- let's run down the other key specs: The OS is Symbian Belle; the engine is a 1.3GHz single-core chip; the display is 4-inches corner to corner but its resolution is a Nokia-style 360 x 640 (nHD). There's 512MB of RAM and 16GB of on-board storage that is thankfully expandable via microSD. 

Nokia Lumia 920 

 Nokia Lumia 920 is a smartphone developed by Nokia that runs the Windows Phone 8 operating system. It was announced on September 5, 2012, and was first released on November 2, 2012. It has a 1.5 GHz dual-core Qualcomm Krait CPU and a 114 mm (4.5″) IPS TFT LCD display, as well as a high-sensitivity capacitive touchscreen that is covered by curved Gorilla Glass. It supports inductive charging (it can be charged by being placed directly onto a charging pad) and is compatible with Qi Inductive Charging; further, it features an 8.7 megapixel PureView camera with optical image stabilization for still images and videos. 

Huawei Ascend Mate 

 The Huawei Ascend Mate is an Android smartphone manufactured by the Chinese telecommunications company Huawei. The Ascend Mate was officially unveiled at the 2013 International CES in Las Vegas, and is expected to be released in China in February 2013 with an international release to follow in March.

In size, the device straddles the large end of smartphones and the small end of tablets and is thus known as a phablet — a portmonteau of phone and tablet. 

ZTE Grand Memo 

 ZTE caught us by surprise, outing a Snapdragon 800-infused version Snapdragon 600 variant of the Grand Memo at its MWC 2013 presser. The device, which still features the same 5.7-inch (720p) display, 13-megapixel rear camera and 3,200mAh battery, is nearly indistinguishable from the other variants we've seen. But for this go-round, ZTE's added in Dolby Digital Plus Surround for a superior audio experience and an extra GB of RAM. Its external chassis may have remained the same -- plasticky and lightweight -- but the difference in this 8.9mm-thick Memo's real-world performance is immediately noticeable. 

Motorola Droid Razr Maxx HD

Sitting at the top of the company's 2012 lineup, it's the most impressive Android handset I've ever used, and it had better be considering its sky-high sticker price. If you're willing to spend the big bucks, though, you get a lot to like, such as swift dual-core processing, a 4G LTE data connection, and a gorgeous 4.7-inch HD AMOLED screen, and then there's that battery. As it's equipped with the same legendary 3,300mAh high-capacity battery that propelled the Droid Razr Maxx to greatness, saying the Razr Maxx HD has staying power is a laughable understatement.

Motorola Droid Razr Maxx 

The Motorola Droid Razr Maxx was recently updated to run Android 4.0 Ice Cream Sandwich. Be sure to check out our hands-on with the phone and its refreshed software. Motorola ups the Android ante with its new creation, the Droid Razr Maxx. Not only does this superslim handset come equipped with all the outstanding features that graced the first Droid Razr, Motorola has thrown in an energy-dense 3,300mAh battery, too. Promised to run for days on end, the Maxx could be the longest-lasting, most powerful smartphone we've ever seen.
