Verizon's CTO Tony Malone fired back a little with this remark: "We have kept our promise, not through ad agency and ad complains but with real performance." Malone is referring to T-Mobile's massive ad campaign around what T-Mobile calls its 4G network and phones. He suggests that Verizon has done more than talk; he says that Verizon's projected LTE network speeds have been proven-and then some--in the marketplace so far.

"We expected some early speed bumps with our launch, but they have been few and far between." Malone said.
