New T-Mobile myTouch 4G ad takes aim at Sprint, AT&T and Apple iPhone
The ad also has a tag line calling T-Mobile America's largest 4G network. That is a direct shot at Sprint. While Sprint has called its broadband network 4G, T-Mobile's HSPA+ pipelines have delivered faster speeds. Up to now, the carrier had been content to say that it offered 4G speeds. Now that the nation's fourth largest carrier is continuing to rollout HSPA+ all over the country, and has two handsets that are HSPA+ enabled, they are now calling the service 4G. By a technical definition, neither carrier is actually offering 4G in the States.
