We're known for a while that Deutsche Telekom (OTC:DTEGY) unit T-Mobile is intent on disrupting rivals such as AT&T (NYSE:T) and Verizon (NYSE:VZ) to win subscribers here in the U.S. A deal with Apple (NASDAQ:AAPL) has been in the works since at least early December.

We're due a glimpse at what else the telco has planned at its "Uncarrier" event scheduled for Tuesday. A likely topic: LTE. GigaOm reports that T-Mobile is on the verge of launching hyperfast wireless broadband service in eight cities, including Denver, Kansas City, Las Vegas (both Kansas and Missouri), New Orleans, San Diego, and Seattle, as well as New York and the San Francisco Bay Area.

In the following video, Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova says the rollout comes at the right time, especially in underserved markets such as Denver. Making fast LTE service available to iPhone owners in these areas could lead to a windfall of sign-ups of disgruntled AT&T and Verizon users, Tim says. Do you agree? Disagree?
