Yes they do.
I know that the Evo does not allow for simultaneous WiMax+CDMA.
I am guessing LTE does since it is a GSM technology but I don't really know.
Well LTE, in Verizon's case, is still going to have a CDMA backup in it.

Omg seriously?
1. My evo does voice ++ data at the same time on wimax just fine. On my epic as well.
2. LTE is not a GSM technology. It never was. It's a completely different standard.
3. Cmda2000 won't be phased out for at least another ten years. The original AMPS launched in the early 80s barely got phased out a few years ago, nearly 30 years after deployment.
the only reason your doing voice and data at the same time is because your voice is still being carried on the 1xrtt genius. While your data goes over wimax also LTE was a GSM tech it was the natural progression for GSM not CDMA . Here you go!

LTE
Long Term Evolution (LTE) is the next step from 3G/WCDMA & HSPA for many already on the GSM technology curve but also for others too, such as CDMA operators. This new radio access technology will be optimized to deliver very fast data speeds of up to 100Mb/s downlink and 50Mb/s uplink (peak rates).
Designed to be backwards-compatible with GSM and HSPA, LTE incorporates Multiple In Multiple Out (MIMO) in combination with Orthogonal Frequency Division Multiple Access (OFDMA) in the downlink and Single Carrier FDMA in the uplink to provide high levels of spectral efficiency and end user data rates exceeding 100 Mbps, coupled with major improvements in capacity and reductions in latency. LTE will support channel bandwidths from 1.25 MHz to 20 MHz and both FDD and TDD operation.
Although both LTE and WiMAX use the OFDMA air interface, LTE has the advantage of being backwards compatible with existing GSM and HSPA networks, enabling mobile operators deploying LTE to continue to provide a seamless service across LTE and existing deployed networks.
Several major mobile operators, including some running CDMA networks today, have indicated they will adopt LTE in the next few years. Japanese mobile operator NTT DOCOMO has said that it is aiming to launch a commercial LTE network by the end of 2009, while in the U.S., the largest CDMA operator, Verizon Wireless, is currently trialing LTE with a view to launching a commercial LTE service in 2010.
LTE- Advanced
LTE-Advanced extends the technological principles behind LTE into a further step change in data rates. Incorporating higher order MIMO (4x4 and beyond) and allowing multiple carriers to be bonded together into a single stream, target peak data rates of 1Gbps have been set.
LTE-Advanced also intends to use a number of further innovations including the ability to use non-contiguous frequency ranges, with the intent that this will alleviate frequency range issues in an increasingly crowded spectrum, self back-hauling base station and full incorporation of Femto cells using Self-Organising Network techniques.
LTE-Advanced will be 3GPP
How do you think gsm carries voice and data at the same time genius.
An that useless paragraph, yeah that's all marketing speak from the guys trying to sell lte licenses. LTE has nothing in common with GSM. Do you even know how each of the respect technologies works or are you just a pro marketing speak regurgitator?
How come everytime someone puts information, articles, proof etc etc you always come back like your so f'n smart. I'm gonna say this I'm done wasting my time with your pompous ass. If you like sprint and wimax so much good just dont jump on people with other networks and always think your smarter. I do know how it works imbecile but since you seem to know so much I will just stop wasting my breathe
Here's a bonus. GSM has more in common with an Mp3 than a real air interface, like TDMA. (Which is what GSM, an audio codec, runs on.)
yes I know I know that TDMA was the original network that aT&T ran before it was Cingular than it switched over to GSM and now the GSM has been overlayed with UMTS and eventually LTE. I know that. I also know the difference with CDMA technologies I know they also can be worked into LTE but the optimal backward compatibility for LTE was originally GSM
Att still uses TDMA

And that is the advantage AT&T is going to have over most of their competitiors for a while. If you have their LTE and travel out of an LTE area you will be stepping down to HSPA+
If you have VZ's LTE and travel out of area it will take you a while to reconnect data as you switch down to CDMA or whatever because you may need to swap internal radios real time.

Ummm no. They already have lte radios that are fully backwards compatible with CDMA 2000. Do you guys know what air interface hspa+ uses?
The switch isn't seamless my friend has a data card that runs on Verizon and when his laptop switches from LTE to 3G there is a slight freeze
Never said they implemented it yet lol. that hardware was rushed out so they could say they had a 2010 launch.
Well hopefully they fix that because on a phone that would suck lol
There are always seams.
The question is how picky are you and will you be able to pick them out.
The handoff from 3G to EDGE on at&t is imperceptible and I'm sure the LTE to HSPA+ will be the same
just because you don't percieve it doesn't mean there are not seams.
At any rate... I wonder if now that we are getting better services.. if you go from lte to edge your gunna feel it.
Well you wouldn't go from LTE to edge. The backhaul will be 3G were LTE is launched
