10:05 AM -- T-Mobile US Inc. just got personal in the US mobile data broadband battle, although it's bending the truth to its benefit.

In a new commercial reminiscent of Verizon Wireless 's Droid campaign against AT&T Inc. (NYSE: T)'s iPhone, T-Mobile takes on everyone's favorite wireless punching bag, calling out AT&T for not having the "4G" network that T-Mobile is claiming to own.

Of course, whether T-Mobile's 21Mbit/s High-Speed Packet Access-Plus (HSPA+) network, which it rolled out in six additional cities today, is truly fourth generation is up for debate. (See ITU Says '4G' Isn't , 4G World: Faster 3G in US – Charting HSPA+, 4G World: AT&T to Go to 21Mbit/s HSPA+ in 2011?, and T-Mobile's HSPA+ Rivals Clearwire, US LTE Speeds.)

The new commercial also touts the HSPA+ myTouch 4G, launching today, along with the Dell Technologies (Nasdaq: DELL) Mini 10 HSPA+ netbook. (See T-Mobile on a Roll.)



So what's WiMax operator Sprint Corp. (NYSE: S)'s response to T-Mobile's claim of having "America's largest 4G network"?

Sprint 4G president Matt Carter says, "Halloween is over -- it's time for T-Mobile to stop dressing up like their favorite super hero -- Sprint 4G."

Halloween may be over, but the important holiday selling season is upon us. We'll see whose message resonates the most with consumers.
