Boy Genius Report briefly notes that it has received a tip that Verizon may be preparing to roll out network technology that would enable simultaneous transmission of voice and data, a feature that both Apple and AT&T have trumpeted on the iPhone.
We have been told that when the mythical Verizon iPhone materializes, assuming it's not a LTE unit, it might launch with VoRA; Voice over Rev. A. According to our source, Verizon has been testing VoRA as a precursor to VoLTE, and as long as the network upgrade timeline and iPhone release are aligned, we should see this happen.
Implementations of the CDMA2000 standard currently used by many carriers around the world, including Verizon, do not support simultaneous voice and data, a drawback viewed by many as significant in comparison to the UMTS standard employed by AT&T and all other current iPhone carriers.

Thought that only applied to EDGE/GPRS? If you are on 3G, you can receive phone calls while surfing the net right?

Verizon costs way to much.
In my city, they aren't any better than AT&T. Just did carrier testing for work.
Verizon customer service, whom I have to call everyday for work, blows.
No SIM cards.

I'll stick with AT&T. Maybe jump to T-Mobile if they get an iPhone down the road. Which will probably be the same time, if not sooner than Verizon due to SIM cards.

Why is it important that voice and data be performed simultaneously? I have never come across a time in which I "needed" both.

I currently carry an iphone (personal phone) and a verizon phone for work. Even if verizon doesn't get the iphone, it will be a great day if this happens.

I think a call gives priority and will interrupt your data over 3G, but you can't use both simultaneously pending a possible upgrade. You can on wifi though. GSM is the one that won't work on edge but does on 3G.

Not a big deal for me as I've said before, but still great news if it happens. It's hard to imagine exclusivity continuing then.

This is all the more proof that Verizon is getting the iPhone at some point in time. Can't wait for AT&T to plumit!
No it's not - even if this happens (and there is no evidence to suggest that this is true or that this applies to VZW's current infrastructure, much less a time frame), Apple can still elect to keep the iPhone on AT&T.

Lets face reality, we are more likely to see it on TMobile than VZW.

One very simple example: you are driving, using your smartphone for GPS-enabled turn-by-turn instructions, and you have an incoming telephone call.

Personally I've been very surprised at how often I use web+data while talking on the phone. Helping a friend with directions, sending my mom an email with photos while talking to her and walking around the farmer's market, streaming internet radio and then receiving a call... it happens a lot.

I certainly won't be willing to switch to any other service unless they have that working. Before I owned the iPhone, I probably would have said "that's silly I'd never use that". Now that I use it almost daily... I can't imagine being without it!

Verizon will not get the Iphone till they get LTE next year. Apple will not make a CDMA iphone...but they might make a CDMA\GSM iphone hybrid.

Not terribly familiar with how exactly these standards work, but one of the things VZW has said about an iPhone coming over to their network is that they wouldn't run into the troubles that AT&T has with dropped calls since voice/data are separated. Would transmitting voice over EVDO rev A negate this advantage? I'm happy enough with AT&T, I've only had one or so dropped calls a month since I switched, but I was just wondering.

So AT&T has a huge network strain due to the iPhone. Once most people jump ship and go to Verizon their network will be trashed and AT&T's will be relieved of most of the stress. So my 3 Mbps 3G speeds will increase a bit and be more consistent.

Again... this is a myth. LTE does not mean "the end of CDMA." VZW LTE phones will still have to be BACKWARDS COMPATIBLE. Meaning, the phones will *still* have to support CDMA.

So, if and when the iPhone does come out for VZW (which I believe is an eventuality) it will STILL have to be CDMA compatible.

I have the this same theory minus the VZ network being trashed. When everyone jumps ship to VZ, that should hopefully speed things up on AT&T's side.

Why not? LTE isn't going to be 100% across the nation for a couple of more years. Some reports say that only 250 million will get LTE coverage by 2015. That's still over 60 million that will use current technology. Just like the iPhone falls back on EDGE/GPRS when there is no 3G, LTE will fall back on CDMA when there is no LTE. Believe it or not, CDMA isn't only used in the US.
