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.

Founded in 1999, TeleNav was one of the first companies to deploy GPS navigation on a cell phone in North America. Now, the company has more than 11 million paying end users.

What's next? TeleNav has filed for an IPO.

The flagship of the company is the GPS Navigator, which is more than just a GPS device with cool features like real-time traffic alerts, weather content, route-planning and so on.

While more and more software becomes free, there is one market for which consumers and businesses are willing to shell out money. Yes, it's security software.

A mega player in the space, McAfee (NYSE: MFE), reported its latest earnings report Thursday, a day after its main rival Symantec (NASDAQ: SYMC) reported its own quite strong results.

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.

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

• Altria Group Inc. (NYSE: MO) Q3 earnings beat by a penny but sales fell short of expectations; shares fell.
• AMR Corp. (NYSE: AMR) reported a Q3 net loss and plunging revenue but also raised $4 billion in cash.
• BB&T Corp. (NYSE: BBT) topped Q3 earnings expectations but said bad-loan provisions nearly doubled.
• Boeing Co. (NYSE: BA) missed estimates and posted a Q3 loss due to delays for a couple of jet products.
• Capital One Financial Corp. (NYSE: COF) shares rose after it reported better-than-expected Q3 numbers.
• Coca-Cola Co. (NYSE: KO) posted a better-than-expected Q3 profit but sales fell short, and shares fell.

Despite largely positive corporate earnings reports, investor caution has set upon Wall Street. For the third straight day stocks are set to move into negative territory, with futures showing the three major U.S. indexes heading lower ahead of Thursday's opening bell.

Some blamed Wednesday's near 1% drops in the Dow Jones industrial average and the S&P 500 on a late-day sell-off driven by the latest Beige Book survey from the Federal Reserve that showed the economy is ever so slowly emerging from recession -- too slowly, it would seem, for investors.

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.

It goes without saying that one investment theme favored here concerns companies with demonstrated business models, which is why I'm Reiterating my Buy rating for AT&T (NYSE: T), first recommended on July 9, 2009 at a price of $25.89.

AT&T's shares have meandered somewhat since the February Buy rating, but that in no way changes T's low-risk, decent-return-on-equity story.

The Street.com's Jim Cramer says that reasonable people who believe the market is a reasonable place to make money are getting back in.

People are getting back to even. In the last 72 hours I have spoken to about 500 investors -- or at least 500 book buyers! -- many of whom have told me they recently either got back to even, having dodged the big decline or gotten in near the bottom, or are actually up nicely because they saw the opportunity in March and rode it back up.

I always figure when you meet people it is strictly anecdotal. But when you meet 500 of them it crosses over into empirical. Here's what I saw of this particular cross-section.

AT&T (NYSE: T) fell from a high of almost $43 to less than $22 in a little over a year. T formed a long-term bottom, finally breaking out at $27 after executing a gold cross (confirmation of a long-term bull market).

But profit-taking in the past two weeks has caused a retrenchment back to support at $26.50.

The stock could pull back more, but its high quality and visibility make this the bluest of blue chip stocks, with a dividend yield of more than 6% and a strong buy recommendation by S&P (five stars).

When selecting which stocks to buy, ratings from agencies like Standard & Poor's can be useful in creating a balanced portfolio.

But did you know technical analysis is the most accurate way to predict where a stock -- or the market for that matter -- is going?

Technical analysis is more of an art than a science, but when used correctly it can boost your profits to new heights. I took a look at stocks that S&P has a four- or five-star rating on and analyzed their charts to come up with six great technical trades for you.

AT&T Inc. (NYSE: T) has seen massive negative publicity come in from earlier in the summer to know in regards to its policies on the Apple Inc. (NASDAQ: AAPL) iPhone it currently has an exclusive on. After all, that $99 or $199 purchase was not giving customers complete control over over the freedom to do what they wanted with those precious iPhones.

When the AT&T/Google/Apple situation flared up recently, it caused the microscope on AT&T's strict controls on the iPhone to become even more intense.

Wall Street appears ready to claim a third straight day of gains as stocks continue a rally cheered by brighter economic news and expectations of higher corporate profits. All three major U.S. indexes -- the Dow Jones industrial average, the S&P 500 and the Nasdaq composite -- were higher in premarket trading Wednesday morning.

Yesterday, the Dow Jones industrial average had its second-straight day of double-digit point gains, picking up 131.50 to end at 9,731.25 after Australia boosted interest rates citing an improved economy and earnings expectations that rose for the just-concluded third quarter.
