AT&T (T) recently announced its proposed acquisition of T-Mobile in a cash and stock offer valued at roughly $39 billion. This is a significant announcement given the size of the two companies and since there was speculation that Sprint (S) might look to acquire T-Mobile. Sprint's shares were down 14% on this news. AT&T's move pits it firmly against Verizon (VZ) as both operators continue to build out their 4G networks.

Our price estimate for AT&T's stock stands at $35.80 which is around 40% ahead of the market price.

Verizon (VZ) primarily competes with Sprint Nextel (S) and AT&T (T) in the mobile subscription plan business. The average monthly fee that Verizon's postpaid wireless subscribers pay for wireless service, excluding data service, has been consistently declining over the past few years. The decline in pricing is mainly attributable to nearing saturation of the U.S. cellular market, creating fierce competition among telecom players to maintain and increase their market share.

A successful Verizon-iPhone (AAPL) deal and rising data revenues from smart phone penetration could, however, offset declines in average mobile plan prices.

If Verizon (VZ) does eventually offer Apple's (AAPL) iPhone, there is little doubt it would be a nice boost to business. At the same time, the phone's exclusive carrier, AT&T (T), would suffer. There would also be problems for Sprint (S), which would likely see customer defections.

Of course, the wild-card is: how big would the impact be? Well, according to a recent survey from Morpace Omnibus, over half of Verizon customers would move over to the iPhone. Consider that the company has more than 92 million customers across the U.S.

Goldman Sachs (GS) was quite the busy brokerage this morning, as it trekked through the financial sector and also issued a number of other upgrades, including one for Sprint Nextel (S).

The brokerage upped Sprint to buy from neutral, issuing a $6 price target, a nice elevation from the previous target of $3.50. Goldman noted that the reason for the upgrade is churn, and that the company is "about to move the needle." Goldman stated, "Sprint's gross add/upgrade activity slowed sharply in 2008, which ironically should benefit the company over the course of 2010 as the logical pool of churn subscribers is reduced." The upgrade comes basically from a glorified hunch.

Sprint Nextel (S) will again be using its CEO to try and explain to potential customers why they should choose the beleaguered telecom provider for their wireless calling and data needs. Using the marketing catchphrase "Our $69.99 is worth more than their $69.99," Sprint CEO Dan Hesse will be featured in a new advertising campaign to explain why Sprint offers so much more value for each customer's money than its two larger competitors, AT&T (T) and Verizon Wireless.

While Sprint Nextel (S) continues to leach wireless customers to the larger competitors, it is propping itself up by taking the lead in prepaid wireless), and by recently winning the top spot in business customer satisfaction for both wireless voice and wireless data services from a survey of large business decision makers.

Why isn't that success translating into more contract wireless customers in the consumer sector?
