Sprint announced on Wednesday that it expects to activate its upcoming 4G LTE network in Baltimore and in Kansas City. The carrier has already said that it will flip the switch on its first 4G LTE networks in Atlanta, Dallas, Houston and San Antonio by mid-2012. The carrier’s first LTE devices will include Samsung’s Galaxy Nexus, the LG Viper 4G LTE and the Sierra Wireless Tri-Network mobile hotspot. Sprint said it also expects to improve the 3G coverage in each of the aforementioned markets. Sprint’s CEO Dan Hesse also said Wednesday that 86% of the phones his company sold during the fourth quarter were smartphones and that 66% of Sprint’s subscriber base now use smartphones, and the carrier’s 4G LTE network will certainly benefit any smartphone user that may be looking for faster download and upload data speeds. Sprint’s full press release follows after the break.

With Samsung’s high-end TV sales doing well, the company is now looking to launch cheaper television sets according to Reuters. Demand for lower-end TVs has been on the rise in recent months, with major South Korean retailers teaming up with local manufacturers to provide flat-screen models that are as much as 40% cheaper than Samsung sets. “As long as there’s demand, we’re open to get into that segment,” Samsung’s executive VP of visual display, Kim Hyun-suk said. “We’ve been preparing to introduce cheap models and have been studying to optimize production costs and retail prices. Those models will be ready for sale in one or two months.” Samsung is the world’s largest TV manufacturer and is aiming to sell 50 million units this year, with half of those shipments being Internet-enabled smart TVs.

Samsung has confirmed that the company will not be holding a press event at this month’s Mobile World Congress trade show, reports to PCMag. At last year’s event the company introduced the Galaxy S II smartphone and in 2010 it announced its Bada mobile operating system. Samsung may still have product introductions at the show, however it will not debut them on the big stage. The company previously confirmed that the highly anticipated Galaxy S III smartphone would not be announced at the event, and BGR exclusively reported in December that Samsung has plans to unveil a new high-end tablet with a high-definition display at Mobile World Congress, though the status of those plans may have changed in light of this new development. The show runs from February 26th until March 1st.

The next-generation iPad will feature a larger battery and a new camera, according to RepairLabs. The website obtained what it claims to be the rear shell of the upcoming iPad 3 from an industry insider in China. After examining the shell and comparing it to an iPad 2 case, RepairLabs noticed the mounts for the logic board were quite different, meaning the board itself will likely be a different shape. The rear case also apparently reveals that the iPad 3 will include a larger battery pack, in line with earlier rumors. The device is also expected to have a “different camera” as well, and the site suggests the front display will also be new. There has been speculation that the next-generation iPad would be slightly thicker, but the site claims that could be false after examining the rear case. Apple is expected to unveil the iPad 3 next month.

Yesterday it was revealed that the popular social networking app Path was uploading entire iPhone address books to the company’s server. The data uploaded included full names, phone numbers and email addresses, and the app uploaded all this data without ever asking for permission. Dave Morin, Path’s co-founder and CEO, admitted fault on Wednesday through the company’s website and announced an update to allow users to either opt in or out of the contact collection feature. “We believe you should have control when it comes to sharing your personal information. We also believe that actions speak louder than words,” Morin said. “So, as a clear signal of our commitment to your privacy, we’ve deleted the entire collection of user uploaded contact information from our servers. Your trust matters to us and we want you to feel completely in control of your information on Path.” The company maintains that when data is transmitted to its servers, it is always sent securely through an encrypted connection and protected by industry-standard firewalls.

Amazon on Wednesday announced that it has entered into a new agreement with Viacom to provide a larger selection of television content to its Kindle Fire and Amazon Prime customers. Under the deal, Amazon’s customers will have access to episodes of The Real World, Chapelle’s Show and the The Sarah Silverman Program from Comedy Central, as well as a number of hit shows from Nickelodeon. “This deal with Viacom brings Prime customers and Kindle Fire users thousands of comedies, kids’ shows, reality TV and much more from some of the best cable networks available,” Amazon’s director of video content acquisition Brad Beale said. “We now offer more than 15,000 movies and TV shows in Prime Instant Videos and are working hard to add even more great content.” Amazon’s full press release follows after the break.

There’s no question that Nokia is betting big on the success of Windows Phone, and we have to admit that it has already unveiled several of the best Windows Phone handsets out there. But the Finnish phone maker is reportedly so convinced that Windows Phone will succeed that it doesn’t have a backup plan of any sort. ”Plan B is that Plan A is to succeed,” Nokia manager Victor Saeijs is said to have told Swedish financial newspaper Dagens Industri. We know Nokia is cooking something up for its low-end phones so all of the vendor’s eggs really aren’t in one basket, but its good to see Nokia so confident in its strategy. Nokia will reportedly unveil at least one new high-end smartphone later this month at Mobile World Congress, and we’ll be on hand to bring you all the news as it breaks,

Apple recently published eleven new profiles for various iPhone-operators that point to a potential iOS 5.1 release date, according to YourDailyMac. The files include references to iOS 5.1, and they mention an update launch date of March 9th, indicating an iOS update could be released around the same time for the iPhone, iPad and iPod touch. The profiles are intended for operators in Japan, France, Greece, Finland and Sweden, and will ensure network connectivity after an update is downloaded. There is also speculation that Apple could release iOS 5.1 along with the announcement of the next-generation iPad, which is rumored for to be unveiled sometime next month. Hit the break for an screenshot of an iOS 5.1 mention with the code of an operator profile.

Protesters plan to stage a demonstration tomorrow in an effort to take Apple to task for partnering with Eastern manufacturers repeatedly accused of mistreating factory workers. Change.org and SomeOfUs have combined their efforts to raise awareness of poor working conditions in factories operated by Foxconn that manufacture consumer electronics for Apple and other vendors. The two organizations have gathered more than 250,000 electronic signatures on petitions that call for Apple to demand improvements be made to the working conditions in the factories that build iPhones, iPads and other Apple products. Representatives from both groups will join protesters on Thursday at 10:00 a.m. at Apple’s new Grand Central Terminal retail store to deliver the signed petition to Apple. “I have been a lifelong Apple customer and was shocked to learn of the abusive working conditions in many of Apple’s supplier factories,” Change.org’s Mark Shields said in a statement. “At Foxconn, one of Apple’s biggest manufacturers, there is a history of suicides, abusive working conditions, and almost no pay. These working conditions are appalling, especially for Apple.” The groups’ full press release follows below.

Contrary to a number of reports that have suggested otherwise, ARM-powered Windows 8 devices will likely be able to run full desktop applications. Microsoft had failed for some time to provide a straight answer as to whether or not ARM-powered devices would be limited to simply running Metro-style applications. However, ZDNet‘s Mary Jo Foley noticed a Microsoft post that specifically discussed power states on Windows 8 ARM devices for “both desktop and Metro style apps,” which clearly suggests that support for desktop applications will be included. Microsoft still hasn’t officially confirmed this, but as Mary Jo Foley points out, we suspect that Microsoft was diligent with its writing and that it didn’t just drop in a reference to desktop support accidentally. We’ll likely have to wait just a little longer until the official word drops, but for now it appears full desktop applications will be supported on Windows 8-powered ARM devices.

I love my iPhone. In fact, I’ve loved every iPhone Apple has launched since the first model was unveiled in 2007. Slowly but surely, Apple has introduced new features and eliminated upon almost every major gripe people had with iOS to push the limits of what we expect from a modern smartphone, and also to keep the platform on par with or even ahead of the competition. Copy and paste, MMS, background apps, multitasking, notifications, folders and much more have been added over time. There is one thing that makes me hate my iPhone every single day though, and I hope Apple is going to address it soon. I need more control over my alerts.

A recent study showed that social networks like Twitter and Facebook are potentially more addictive than cigarettes or alcohol, and now we may have an idea why. A group of scientists from MIT in Massachusetts, IULM University in Milan and two other laboratories in Italy found that people showed physical and psychophysiological responses while using Facebook similar to those exhibited by people while playing a musical instrument or engaging in other creative activities. Beyond wanting to use Facebook for obvious reasons such as keeping up with friends and sharing photos, people may actually be seeking out the chemical responses they experience while browsing social networks.

Information has been appearing in dribs and drabs about Nokia’s last Symbian smartphone, the Nokia 803, but a trusted source of ours has come through with some details that vary a bit from earlier reports. For starters, the Nokia 803 will run Symbian Belle and serve it up on a 4-inch AMOLED display instead of the smaller 3.5-inch screen that had been reported. An HDMI-out port, microSIM support and NFC are all a go as well. We have also been told that the Nokia 803 will feature one of the largest camera sensors — if not the largest camera sensor — ever seen on a mobile phone. The Nokia 803 is currently expected to be released in the May timeframe.
