What do Michael Steinhardt, Lord Rothchild, Rupert Murdoch, and Howard Jonas have in common? Oil shale and IDT shares, obviously.

IDT Chairman Howard Jonas has presided over an eccentric -- and so far brilliant -- diversification of his telecom company into the oil-shale business. And somehow he's attracted some of the biggest moguls in the world.

IDT shares have rallied 600% since the company got into the oil-shale business, recently announcing plans to spin off subsidiary Genie energy. Read about it here.

Silicon Valley startup ConteXtream (yes, the company name spelling is that silly!)  announced yesterday that it landed $14 million in Series B funding to go after a big problem in global networks: Virtualizing the management of broadband applications and content through data centers.

Here's the big picture: As the use of content and bandwidth-intensive applications such as movies, photos, social networking, and games explodes on mobile and wireline networks, service providers are having major headaches managing the bandwidth as well as allocating resources in the data centers to serve these applicatoins. ConteXtream's product, a software solution that loads on commodity PC hardware, adds "smarts" to the network delivery of these applications, allowing service providers to manage the resources on their data centers as a single virtualized "grid."

Let's catch up on many of the public companies and stocks we've been following:

Is there a more explosive economic concept than combining iProducts with China? Didn't think so. In that vein, MarketWatch reports that China Unicom starts to ship iPhone 4 in China next month.

Our mind is boggled by the concept of hundreds of millions of frenetic Chinese citizens roaming the fastest growing country on earth clutching iPhones and iPads.

On to the rest of the news:

Very interesting article by Peter Kafka in AllThingsD this morning about Time Inc.'s frustration with Apple. Apparently Time executives are mystified as to why Apple won't give them control to sell their own subscriptions via an app for the iPad.

Well, I'll tell you why: Apple loves to control the billing relationship. They don't want to give it up. This was the brilliance of iTunes and how they ended up taking control of digital music from the music industry. It was the music industry's huge strategic error. Apple knows that if they control the billing relationship, they control the access to the customer, and therefore can dictate the terms of just about any ecommerce relationship.

Why Time Inc. executives are so "mystified" by this is a mystery to me. Apparently their magazine executives are not talking to executives in the same company that got reamed in the music business. Apple wants to control billing, they want to control pricing, and they want to control the consumer. Period. You want to try to mess with that? Take a hike.

This is one reason why I don't think the iPad will be the "savior" of the media industry that everybody has made it out to be. Unless Apple opens up, and starts sharing a bigger piece of the pie with content and applications producers, it will be the same movie all over again.

Calix shares got hammered pretty hard on Friday after the company issued weak earnings guidance on the quarter. But investors might have been panicking about a whole lot of nothing.

In fact, more intrepid investors might look at why the earnings forecast were down: More R&D spending, possibly related to more big customers. But on Friday this did not matter, investors were in no mood for optimism. The earnings started out well enough: The company announced record revenues that were up 50% from the year-earlier period. In the pre-market, shares were up 10%.

Then the conference call came. The company gave revenue guidance of $70-$75 million and said earnings would only be in the 4 to 8-cent range. Most analysts had earnings of 14 cents or so. Most analysts were also expecting $80 million in revenue.

One of the themes we've been following here is the buildout in more telecom connectivity -- whether it be Ethernet connections or all those data connections to mobile-phone towers -- and Adtran's earnings appear to bear that out.

The Alabama-based networking and telecom equipment company handily beat analyst estimates, announcing quarterly Earnings Per Share (EPS) of .44, whereas consensus expecations were for .35. The stock was trading up 7% -- about $2 -- to $30.90 in midday trading.

I've been poking around Telecom New Zealand (NZT) for quite a while. It first showed up in a dividend stock screen when the dividend was paying about 8%. Forbes' Ken Fisher, who is a pretty good stock picker, recommended it. Now the stock is lower and the dividend is at about ten percent.

What happened?  They recently reduced guidance. Then the CFO left. But as the stock goes down, the dividend goes up. This company has generous free cash flow -- somewhere in excess of $150M in 2010, likely. It's got $1.5 billion in debt, but it also has EBIDTA approaching $1B, so it is adequately covering the debt payments and the dividend.

The forward P/E is about 11. Basically, I feel lucky that I waited to buy this stock, because it looked like it was cheap, and then it got even cheaper. But now that it's fallen to a level of about $6 and is paying 10% dividend, which is almost irresistable to me.  I think it's worth a shot. After all, we are talking about a telecom services stock in one of the healthiest regiona economies in the world.

With this week's bounce off of $6, the stock could be forming a long-range double-bottom. A buy here with a stop at $5.50 seems like the right thing to do.

I recently penned a column for Light Reading on the arrival of 4G and what it will mean for the large global service providers. I think this is a watershed moment for the telecommunications industry and not many folks seem to be paying attention to it.

The business models of the major service providers are about to change radically -- as they go from a heavily regulated, profitable, "utility" model of landline-phone service to the Wild West of the mobile Web. in the pre-4G world, the bulk of their revenue came from predictable and profitable voice services. In the post 4G-world, they will have to provide larger amounts of commoditized data at a lower price point. The bottom line is that 4G is expensive and their margins on mobile data are much lower than voice.

Not only that, but data traffic will predominate the traffic and revenue on 4G networks. When 4G networks get rolled out in 2011-2012, the delivery of mobile data will increase by an order of magnitude. This will present challenges to them on the cost front.

Here are a few facts you might want to follow:

• The global mobile data revenues reached $220 billion and mobile data now contributes 26 percent of the overall global mobile service revenues, according to Chetan Sharma Consulting.
• 2009 also marked the year when the global data traffic (monthly) exceeded the global voice traffic. In the US, the yearly mobile data traffic exceeded the voice traffic for the first time.
• It is expected that 2009 marked the year that mobile data traffic reached a new milestone of 1 exabyte (EB) or 1 million terabytes (TB). By 2016-17, the global yearly mobile data traffic is likely to exceed 1 zettabyte (ZB) or 1,000 exabytes, according to Chetan Sharma Consulting.
• Over 50 percent of the world's households carry a mobile device, according to Accel Partners.

Don't you love the way that Apple dominates the news? Steve Jobs could put out a press release saying he's going to have his teeth cleaned and it would dominate the news flow on Financial TV. Oh really? Who's the dentist? Will this delay a product release?

Yesterday, of course was the release of the new iPhone 4, which had every tech pundit and their cousin covering every angle. For that reason, I'll keep this post short, giving you a few links to coverage and a few thoughts for what it means for Apple.

The main points of iPhone 4:

• It's slimmer, .37 inches vs. .45 inches for the prior iPhone (PC World review)
• It's got video calling (mirror.co.uk).
• It's got a sharper screen. And a Gyroscope (CNN)
• Actually, they are calling the screen a "retina display," because its density of 326 pixels per square inche allegedly rivals the human retina. Yeah, right Apple (Tom's Guide).
• IOS 4, which includes support for multitasking, iBooks, and other stuff (Mashable).

Okay, so what's it all mean? What's interesting to me is the statement that Apple has made with its last two releases: iPad and the iPhone 4. Have you noticed that Apple and Steve Jobs in particular claim to be "driving industries forward." For example, the message of the iPad as that it will enable the publishing industry to function in the digital world.

But rather than focus on whether or not the iPhone is driving some industries forward I can't help but think how it's driving the telecommunications industry backward. What do I mean by that? It is becoming more evident that the iFranchise is making the telecommunications provider increasingly commoditized and irrelevant.

What's AT&T's role in the iPhone franchise other than to connect the thing to a mobile network and then disappoint users. is AT&T adding any other value at all?

If all of the innovation is coming from Apple, what value are the service providers adding? What does this mean for the future of the mobile telecommunications industyr? Check out the videoconferencing component of iPhone which uses a WiFi connection and could certainly accelerate the trend of Internet communications platforms cannibalizing service provider networks.

Think about that, AT&T: Just look at what's happened to Apple's shareprice when compared to yours. Clearly they are the innovator and you are now the commoditized service provider.

Now, who has derived the most value out of the iPhone franchise?
