AT&T, Inc. (T) has been getting itself into a wad about recent commercials from larger competitor Verizon Wireless. In those ads, Verizon touts its advanced 3G wireless coverage over AT&T's tepid 3G coverage as a way to battle the ubiquitous popularity of the Apple (AAPL) iPhone that no carrier seems to be able an unseat as the phone to exclusively sell.

Last summer, eBay (EBAY) launched its iPhone app, which turned into an instant hit. If anything, it showed that mobile commerce was not a pipe dream as the downloads reached more than five million.

So, in anticipation of the Christmas shopping season, eBay has launched a new iPhone app. It's called "Deals."

Twitter is on the prowl. Though it made its last acquisition more than a year ago, company founder Biz Stone said on Tuesday that it's looking to add to the stable. There aren't any specific targets yet -- at least none revealed -- and Twitter is keeping its options open. The likely pool of potential acquisitions consists of third-party Twitter application developers, which is largely responsible for the micro-blogging service's growth in popularity.

Stone, one of Twitter's founders, said at a Tel Aviv news conference, "As our attention is grabbed by some of these developers, we will take a hard look at them." This refers to companies that develop applications for Apple's (AAPL) iPhone and Research in Motion's (RIMM) Blackberry. It also refers to developers for the Web and desktop, such as HootSuite and TweetDeck.

Apple (AAPL) continues to bring the iPhone to countries outside the U.S. Although its launch in China didn't generate as much fanfare as the company had hoped, things take time to roll into a big ball of success. Apple won't be slowing down international introductions of the handset that changed the wireless game, that's for sure.

As such, South Korea's own LG Electronics and Samsung Electronics are about to see their homeland assaulted by the official introduction of the iPhone for sale into that country. South Korea's KT Corp. and SK Telecom are the reported carriers for Apple's iPhone there, and although the South Korean market may seem like a small potato of opportunity for Apple, the company has been cleared by the Korean Communications Commission to start selling its popular handset.

Google (GOOG) and Apple (AAPL) were once favorite friends. When Google CEO Eric Schmidt resigned from Apple's board of directors, though, the gloves came off. With Apple's venerable and extremely popular iPhone selling for $99 (for the base edition), Google's "Android" phones -- made by several manufacturers and sold by many carriers -- have not matched those low Apple prices. Not any more.

Consumer electronics retailer Best Buy (BBY) is selling the Samsung Moment and the HTC Hero for $99 through December -- matching Apple's iPhone pricing for a two-year contract. That's with no rebates, either. So, the question is this: will Google's Android-powered phones start gaining traction on the iPhone? With AT&T's (T) penchant for poor service and for exorbitant calling plan prices, this may be enough to get those on the iPhone fence switching over to a touchscreen Android phone.

The recession has led everyone with a budget to question ever line. From households to businesses to state and federal governments, nothing is sacred. Finding new ways to get the same result without spending the same amount mean not having to make sacrifices. NASA has been under considerable financial pressure, as many question the value of sinking cash into space travel. So, it has to get creative in justifying its existence ... and in generating excitement about the agency and what it does.

When the space shuttle launches on Monday, 200 thumbs will be at the ready. NASA has deputized 100 of its top fans on Twitter to come to the launch and tweet the experience. These fans are estimated to have more than 150,000 followers, all with the potential to retweet the messages they see. Every click of an iPhone or Blackberry will give NASA more exposure, building the excitement it needs to keep the operation afloat. So, whether you realize it or not, the launch is being brought to you by Twitter, Apple (AAPL) and Research in Motion (RIMM), even if only implicitly.

The future investment stars are already with us. The NYSE Financial Future Challenge, operated by the NYSE Foundation, By Kids for Kids, K12 Inc. and the United Investors Association, is in full swing, with five finalists just identified. To reach this level, the participants had to develop a new product, idea or process that would "excite, educate and motivate their peers" to become interested in the financial marketplace. The eventual winner lurks within this subset and will receive a $2,500 prize -- a great way to get that portfolio started. And, he or she will be feted at a closing bell ceremony at the NYSE (NYX) on January 11, 2010.

The finalists presented a variety of ideas which are sure to generate some buzz. Kelsey Foss, a 12-year-old from Mountainville, NY, proposed a new television show, "Stock Market Tycoon Idol," which would harness the popularity of reality TV while amping up the content. The program would involve the journeys of 10 kids as they seek to make money or lose it, with the possibility of becoming virtual millionaires along the way. The show would be set at a mock NYSE studio on Wall Street, and exports would be brought out to mentor the contestants. The reality TV reach would help engage a younger audience.

Even the thought is hard to believe for anyone who's been watching Apple Inc. (AAPL) over the long run. Once upon a time, the company was presumed dead, while Microsoft Corporation (MSFT) continued its march to market dominance. Today, Apple's $180 billion market value is evidence of a new era. Though it's still behind Microsoft's $250 billion, the company's rapid ascent and substantial market presence make at least speculation of catching up to the Redmond giant worth a few minutes of thought.

Microsoft is currently the most valuable technology company in the world, according to a Reuters report. Even Google, Inc (GOOG), with its astounding brand recognition and position as gateway to the internet, is worth "only" $136 billion. Apple, which was once considered a computer company that sold into education and appealed to some graphics geeks, has reasserted itself as a major global presence.

While Sprint Nextel Corp. (NYSE: S) continues losing hundreds of thousands of customers every quarter, it has actually raised the bar on offering cutting-edge smartphones at the same time. Smartphones, which are slowly but surely replacing the standard cellphone for the typical "always need to be connected" consumer, are helping wireless carriers drum up wireless data revenue to replace the lost voice revenue as customers talk less.

AT&T, Inc. (NYSE: T) has seen incredible gain on the back of the Apple iPhone in the last two years. So much, in fact, that its national wireless network is most likely strained -- causing many an iPhone customer to constantly have problems with their service.

RealNetworks (NASDAQ: RNWK) is profitable again! The online media company that provides music and other entertainment cut its way into the black, getting rid of the costs that were getting in the way. It wasn't much of a profit, only $1.5 million for the third quarter, not even a full cent per share, but it's a hell of a lot better than the $4.5 million loss it sustained in the third quarter of 2008.

Revenue fell 8% last quarter to $140.3 million, just shy of the analyst average of $140.9 million. This trend is likely to continue through the fourth quarter. Music, technology product and game revenues were down. The profit was instead eked out of the supply chain and headcount.

If the Wii were still cool, Nintendo (OTC: NTDOY) wouldn't have had to take a heavy hand to its full-year earnings forecast. The company's profit fell 52% year-over-year for the past quarter, due in large part to a decline in the game's popularity. Demand has slipped, with Sony (NYSE: SNE) and Microsoft (NASDAQ: MSFT) gaining ground with the core market of zealous gamers. Also, it's seen its position eroded by Apple's (NASDAQ: AAPL) iPhone, which is picking up some momentum as a gaming platform.

Nintendo's Q3 operating profit dropped to JPY64 billion ($709 million), falling far short of the analyst estimate of JPY90 billion. For the year ending March 2010, the company has chopped its forecast to JPY370 billion, far lower than the analyst expectation of JPY442.8 billion.

After dominating the gaming industry for the past three years, Nintendo's Wii gave up its position in the top spot to Sony's PlayStation 3 last month. The company has also been hurt by an increase in the value of the yen, which has hurt all Japanese exporters. Yet, even by local standards, Nintendo isn't measuring up. Its stock price is down 28% this year, compared to a 14% increase in the Nikkei 225.

Ever since Apple Computer (NASDAQ: AAPL) introduced the iPhone to the world, other cell phone companies have been working hard to compete. Verizon (NYSE: VZ) is hoping to find success with the Motorola Droid, which will come with a $199 price tag.

The phone will be running on Google's Android operating system, and could be a serious contender against the iPhone, and while most people knew this phone was coming, the real news is that it will start to be sold next week at Verizon's across the nation.

Verizon Communications Inc. (NYSE: VZ) issued Q3 data on Monday. According to the press release, the telecommunications entity made, on an adjusted basis, 60 cents per share. Disappointing, since that's six pennies less than last year's comparable number. However, it was a penny ahead of analyst expectations, according to Reuters.

Of course, when discussing Verizon, what tends to receive focus is cash flow. As we all know, the company is a famous dividend play. Many investors consider this angle to be not only valuable, but an added safety element as well.

Where do you tweet? When? More important, what's normal? Are you some kind of freak?

A recent Gadgetology study by Retrovo.com, a consumer electronics shopping site, seeks to ascertain where the line in the sand is in regards to social media use (and overuse). If you're 35 or younger, regular use of sites such as Twitter and Facebook is common (big shock, right?). It looks to Retrovo like a new addiction may be taking root.
