The future is looking bright for the two main telecom carriers on the Dow, Verizon (NYSE:VZ) and AT&T (NYSE:T). As we see the transition from 3G to 4G LTE data speeds, ushered in by the introduction of Apple's (NASDAQ:AAPL) iPhone 5, opportunity abounds for mobile-service providers with the most 4G exposure.

Verizon is beautifully positioned for this, with 371 markets compared with AT&T's 53. The iPhone 5 will be available through both carriers, but Verizon's domination of 4G markets gives the company an additional advantage in terms of attracting new subscribers. As more and more mobile users gain access to faster data speeds, overall data consumption will increase enormously, benefiting carriers in a big way. Expect to see changes made to smartphone contracts, specifically data plan components.

There's a lot to like about Verizon right now, with its 4.7% dividend (very attractive at today's low interest rate) and a potential upside in catalyst from 4G subscriber growth. However, it's important for investors to understand the implications and potential risks that the iPhone 5 will introduce in the telecom arena.
