statement from the blog of ATT's CTO.
what he says is true and they are careful to label their HSPA+ not LTE, per se, but an evolutionary process on the way to LTE.

More Than One Acronym for Speed
John Donovan
December 01, 2010
In their haste to build LTE networks, some wireless service providers are stinging from their decision not to update their current networks. They have just one way to spell speed, and its LTE.
Theyll tell you that data is the primary mode of mobile communication today, and speed matters.
We agree.
Theyll tell you that LTE is the path to data speed.
Wed agree again, but with some important details that they tend to leave out.
We know about speed. We have the nations fastest mobile broadband network. Our largest competitors wireless network is 60 percent slower on average nationally. The closest competitor is 20 percent slower.
We also know that the best mobile broadband experience is based on consistent speed. Weve delivered five mobile broadband speed upgrades in recent years, including our HSPA+ deployment.
Our HSPA+ network and upgraded backhaul is expected to deliver speed performance similar to initial LTE deployments. That matters, because when we begin commercial deployment of LTE in mid 2011, customers on our LTE network will be able to fall back to HSPA+. As they do, theyll receive a more consistent mobile broadband experience that supports simultaneous voice and data connections and higher speeds than the others can provide outside their LTE footprint.
Customers of carriers who chose not to upgrade their current networks will move in and out of LTE coverage areas as well. But as they do, theyll experience a jarring speed degradation. If theyre online and on the phone when they move to sites that dont support simultaneous voice and data connections, theyll drop one of those connections. And if theyre watching video, its not going to be pretty
More than half of our customers use simultaneous voice and data regularly. Three in four told us that a consistently good speed experience is very important to them. Our technology path forward meets those needs and is the best path to delivering a consistently good broadband experience.
Its not sufficiently appreciated that LTE stands for Long Term Evolution. It will take a long time for LTE to be deployed broadly.
As carriers LTE footprints expand in coming years, the speed of todays networks cant be ignored because theyll play a big part in delivering the mobile Internet well into the future. To serve customers well to give them a great mobile broadband experience were making our fastest network even faster as we transition to LTE.
