John Legere kicked off T-Mobile's event in New York City today with an unrelenting tirade against the carrier's competitors. "Stop the bullshit," the CEO said, referring to the traditional subsidy model being pushed by Verizon, AT&T, and Sprint. "Carriers are really nice to you... once every 23 months," teased Legere, in a no-nonsense presentation even more aggressive than his speech at CES earlier this year. "This is the biggest crock of shit I've ever heard in my entire life. Do you have any idea how much you're paying?" Legere blasted T-Mobile's competitors for locking mobile customers into two-year agreements — a business practice T-Mobile has abandoned with its new "Uncarrier" rate plans.

"There's not a person in the world that would understand how this mess works."

"Customers love smartphones, everyone hates contracts," he said, equating the longstanding industry model to "smartphone hell." He said, "if you come to T-Mobile, you've signed your last contract." The verbal barbs kept coming as Legere touted T-Mobile's just-launched LTE network. To demonstrate his confidence in the carrier's s new strategy, Legere said plainly "if we suck this month, drop us. Go somewhere else."

And months after the AT&T / T-Mobile merger fell apart, there's clearly no love lost between the companies. "Customers don't need another AT&T," Legere chided. "Customers need someone to stop acting like AT&T." Legere eventually departed the stage, but not before he'd made it abundantly clear that America's number four carrier is on a radical new path.
