The joys of a simple Twitter slanging match. Sprint’s CEO Marcelo Claure has taken T-Mobile CEO John Legere’s criticism of his new “All-In” wireless plan badly. It’s like being in a playground with very wealthy people.

Legere—rightly—points out that Sprint’s new initiative has some holes.In response, Claure slams T-Mobile for lying to its customers. Here’s the exchange so far.

Sadly this all happened quite late last night, so Legere still hasn’t responded to Claure. We’ll update when he invariably does.
