The vision of Clearwire (CLWR) is definitely ambitious: to "give you faster Internet at home, at work and on the go, so that people everywhere will have the magic of the Internet with them all the time." This means building a sophisticated network across the country, which does not come cheap.

Tuesday, Clearwire announced yet another financing round, which comes to $1.56 billion. The investors include Sprint Nextel (S), Comcast (CMCSA), Time Warner Cable (TWC), Intel (INTC), Eagle River Holdings LLC, and Bright House Networks LLC.

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.

Cable giant Comcast (NASDAQ: CMCSA) posted Q3 numbers earlier today. It seems like the company is doing well with earnings growth and cash flow, even if revenues moved up a meager 3%.

Adjusted earnings per share grew over 20% to 28 cents per share. According to our earnings preview, the market was looking for 25 cents per share. Operating cash flow increased a little under 3%, but free cash flow went up almost 20%, aided by a smaller amount of capital expenditures compared to the previous year's similar quarter. I'm sure shareholders are more than satisfied with the growth rate of the green stuff over the past three months. Comcast saw excellent expansion of free cash over the last nine months, too.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• AK Steel Holding Corp. (NYSE: AKS) reported better-than-expected Q3 results but shares fell anyway.
• Baidu Inc. (NASDAQ: BIDU) posted strong Q3 results but shares sold off on a disappointing guidance.
• Burger King Holdings Inc. (NYSE: BKC) said lower Q1 earnings fell short of analysts expectations.
• Dreamworks Animation SKG Inc. (NYSE: DWA) topped Q3 profit and revenue estimates, lifting shares.
• Geron Corp. (NASDAQ: GERN) posted a narrower-than-expected Q3 loss, sending shares sharply higher.
• Honda Motor Co. Ltd. (NYSE: HMC) reported lower Q2 earnings and sales on weak demand for cars.

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.

Analyst upgrades:

• Verizon (NYSE: VZ) was upgraded to Outperform from Market Perform at Wells Fargo, which believes Verizon wireline margins troughed in Q3 and that Street estimates have been reset to more achievable levels.
• Texas Instruments (NYSE: TXN) was upgraded to Outperform from Market Perform at FBR Capital, which believes the company is gaining analog market share and shares are attractively valued at current levels. The firm maintains a $31 price target.
• Cablevision (NYSE: CVC) was upgraded at Wells Fargo to Outperform from Market Perform. The firm believes this year's run-up in the stock was primarily due to the company's spin-off of MSG, but the firm believes the stock can rise further based on fundamentals.
• Cabot Oil & Gas (NYSE: COG) was upgraded to Overweight from Neutral at JPMorgan following the company's Q3 results due to valuation and its above-average growth. The firm raised its target to $51.50 from $47.
• RadioShack (NYSE: RSH) was upgraded to Hold from Underweight at KeyBanc, which said that its recovering sales trends were encouraging.
• Travelzoo (NASDAQ: TZOO) was upgraded to Outperform from Neutral at Wedbush as it believes the divestiture of its Asian business coupled with growth in its Fly.com unit will drive 2010 growth. The firm raised its target to $17 from $13.

Dallas-based AT&T Inc. (NYSE: T), the exclusive U.S. carrier for the iPhone, is scheduled to discuss its third quarter 2009 financial results in a conference call Thursday at 10:00 AM ET. You can catch the live webcast of the call on the company's website.

During the three months that ended in September, AT&T revamped many of its retail locations, expanded its global wi-fi presence, and declared a quarterly dividend. Analysts surveyed by Thomson Reuters expect this leading provider of wireline voice communications services in the U.S. to report that earnings grew 6.0% from a year ago to $0.50 per share. But revenue for the quarter is expected to be 1.5% lower to $30.9 billion.

Many investors need income, especially as they reach retirement. They look for ancillary cash flow to supplement their Social Security payments and any retirement benefits from a company for which they've worked. But those aren't the only investors who should be interested in income.

That's because studies show that dividends are a significant contributor to overall performance of a stock. When held for years, a stock's dividend can help diminish the volatility of a stock's price and keep returns reasonable, especially in down markets. Here are five stocks that have decent income as well as potential capital gains. All are exceptionally financially strong.

TheStreet.com's Jim Cramer says Research In Motion's troubles are an exception to the greatness of the mobile Internet theme.

No, this isn't meant to be a bullish article. I am just trying to put Research In Motion (NASDAQ: RIMM) (Cramer's Take) in perspective because I think that people will confuse the greatness of the mobile Internet theme with the hazards of investing in the BlackBerry maker.

First, you have to ask yourself, what really went wrong with RIMM? Was it demand? No, demand was strong. They actually guided to the upper end of units. The issue was average selling price because it has gotten more competitive out there.

"The Dogs of the Dow strategy has a long-term history of outperforming the Dow Jones average," notes technical expert Gerald Appel.

In his Systems & Forecasts, he explains, "The theory is that the highest yielding stocks are undervalued and should have the greatest change of appreciating." Here, he reviews the five highest yielders.

"In calculating a formal track record for the strategy, dividend yields are ranked on the last trading day of each year. However, there is no reason why you are limited to ranking stocks only at the end of the year.

"The current market climate appears favorable for using this strategy to garner investment income, since market risk appears below normal and investment income is getting hard to come by.

Analyst upgrades:

• Deutsche Bank upgraded Garmin (NASDAQ: GRMN) to Hold from Sell as it believes the company's second half of 2009 is tracking better than expected due to retailer restocking. Deutsche raised its target on shares to $33 from $15 but thinks Garmin's long-term trends remain unfavorable.
• Goldman upgraded Fortune Brands (NYSE: FO) to Buy from Neutral citing potential EPS improvement driven by the Home division. Fortune Brands price target to $49 from $45. Note that the firm downgraded General Mills to Neutral from Buy.
• Oppenheimer upgraded FPIC Insurance (NASDAQ: FPIC) to Outperform from Perform to reflect the company's acquisition of Advocate MD and management's commitment to share repurchases. The firm set a $49 price target on the stock.
• PPG Industries (NYSE: PPG) and Olin Corp. (NYSE: OLN) were upgraded to Neutral from Sell at UBS.
• Synovus (NYSE: SNV) was upgraded to Neutral from Underperform at BofA/Merrill.
• Take-Two (NASDAQ: TTWO) was upgraded to Overweight from Neutral at Piper Jaffray.

"Our favorite and steadiest U.S. telecom recommendation is Verizon Communications (NYSE: VZ)," says Martin Weiss.

He explains, "We've always liked their steady-Eddie business and their tradition of paying handsome, predictable dividends." Here's the latest from the "conservative portfolio" section of his The Safe Money Report.

"I remain optimistic that now is a good time to be purchasing high-yielding assets," says growth and income expert Bryan Perry.

Indeed in his industry-leading The Cash Machine, the advisor adds two growth and income picks to his buy list: AT&T (NYSE: T) and Verizon (NYSE: VZ). Here's his assessment.

"Even if you are forecasting a recovery in mid to late 2010, you should be aggressively buying strategic high-income assets over the next three to six months.

TheStreet.com's Jim Cramer says if the company you're looking at is a player in the mobile Internet space, it's probably a good bet.

Does it have smartphone exposure, or doesn't it? That is the question. When I look at what's moving in tech and what's become sullen and gloomy, there's only one compass: smartphones. Think about what's moved this week: Cree (NASDAQ: CREE) (Cramer's Take), Tellabs (NASDAQ: TLAB) (Cramer's Take) and ADC Telecom (NASDAQ: ADCT) (Cramer's Take). These are terrific plays in the smartphone food chain and are included in the "Mad Money" Mobile Internet Index.

ADC Telecom is Chinese Internet infrastructure, and we know that China's spending $40 billion to build out infrastructure that can allow aggressive adoption of smartphones. Tellabs has been waiting for next-generation telecom orders -- smartphones. I think the fact that it announced a giant buyback -- it matters when the stock is this small -- is the signal needed to suggest they are getting orders.
