AT&T may have acknowledged a squabble, but T-Mobile won't settle for anything less than a war. Calling it a "desperate move" to win over customers, boisterous T-Mobile CEO John Legere responded to AT&T's offer to give his customers $200 per line for switching over their service with an attack of his own. "Consumers won't be fooled," Legere writes in a statement posted to T-Mobile's website, "...nothing has changed; customers will still feel the same old pain that AT&T is famous for."

#Randall – you gave us cash & spectrum AND we took your customers with #Uncarrier moves, do you really think you can buy them back? — John Legere (@JohnLegere) January 3, 2014

"I'm flattered that we have made them so uncomfortable!"

Legere suggests that AT&T launched the promotion because it performed poorly over the holidays and is now in an uncomfortable position. Unlikely as that may be, Legere's continued bravado has clearly caught AT&T's attention. He plays up T-Mobile's role as David to AT&T's Goliath, rubbing in his company's newfound favor by pointing out that it's occurred in part because T-Mobile was able to take AT&T's money after a failed buyout attempt, and used that to purchase its spectrum.

Legere also teases an announcement at CES next week that he suggests — a bit hyperbolically — will shake up the industry even more. "Just wait until CES to hear what pain points we are eliminating next," Legere writes. "The competition is going to be toast!"
