Can someone please explain this? Why isn't it possible on Verizon ? And what is voice + data, because it seems to be the main complaint I'm hearing about the Verizon Iphone.

it means that while on phone call on 3g service you can access data functions using 3g so voice call and check email at the same time. you can do this on wifi but only att's gsm signal handles voice and data. trade off. att offers this but verizon will have calls that dont drop so while verizon cant voice and data, att cant either bc they cant even have the voice part working

Very simplified technical differences between GSM and CDMA, which is what Verizon uses on the iPhone, to explain why simultaneous wont happen on current Verizon iPhone :
The coverage area is divided into various hexagonal shaped cells.
This is where I heard the name cell phone came from.
Each cell has a network tower which takes care of the phone in that coverage area.
An analogy for this is a honeycomb on a tree in a hexagonal shaped garden with many flowers (Cell Phones). Honeybees (signal) fly around collecting nectar from each of the flowers and return to deposit it in the honeycomb (Tower).
CDMA stands for Code Division Multiple Access--Many phones using the same spread spectrum. There is one physical channel and a special code for every device in the coverage network.
Using this code, the signal of the device is multiplexed, and the same physical channel is used to send the signal (the codes may or may not change).
An analogy for this is a street(Spread Spectrum) filled with buses. Each passenger (cell phone) has to purchase a ticket (code) to get on the bus (multiplexed signal).
Unfortunately until Apple puts an LTE radio in the phone, it won't be possible to accomplish this.
This will similarly be accomplished by the WiFi radio if you are within a wireless internet signal.
With a seperate wifi radio, the CDMA radio can be used for voice while the wifi radio can be used for simultaneous data.

I was on Verizon for a few years, it wasn't a big issue at all.

You may not remember, but AT&T/Cingular led the nation in call quality/least calls dropped/customer service/etc consistently until the iPhone released. The crazy bandwidth that iPhone users used clogged up the pipes in some metro areas, especially after the iP 3G released. I hope something similar doesn't happen to verizon!

I know this topic isn't about call quality, it's about voice+data; but here is my own assessment:
When I was on Verizon, I had full bars at my house, full 3g for most of my commute, dropped calls regularly (conference calls were a pain when this happened), and I could not surf the net, mms, or email while on the phone.
Since I switched to AT&T: I have full bars at my house, full 3g for all of my commute, drop calls occasionally (though not during my commute like I used to), and I can surf the net, email, and mms while on a call.
Overall, it really depends on how your coverage is in your area. I'm in an area that should have full AT&T and Verizon coverage (including one of the first 32 LTE Markets), and my overall experience has been more positive with AT&T than Verizon, including my Customer Service experience being better.Hear my sporadic ramblings: @liquidzoo on Twitter

So, just to clarify, is the mobile hotspot feature useless if a phone call comes in while my laptop is using the 3G connection from my phone?

Data will be paused once you get a call, so you'd have to reconnect your laptop.
Personally, I don't use data at the same time as voice and I prefer Verizon's reliability. However, I can see that if people are using their phone for hotspots, data cutting off when you get a text message can be a major pain in the butt.
It makes me think all voice/text should be done over VoIP and I think Apple should've announced the VeriPhone but spent a few weeks implementing an LTE antenna to future proof it so this issue becomes null when brought up.
Because of their lack of foresight, AT&T is going to dance around the fire screaming about data/voice at the same time.

Apple has already said they won't be implementing LTE in the iPhone until 2012 (iPhone 6). Mostly due to the fact that they want the network to develop globally and mature before they officially support it.
Once AT&T and T-Mobile have a full roll-out of their LTE network, combined with the Verizon LTE network would be great in terms of data and voice coverage for the iPhone. It is similar in other countries with other carriers who have opted to go with LTE as their "4G" network.
Global stability of the network means far fewer issues once Apple makes the decision to put the antenna in the iPhone.Hear my sporadic ramblings: @liquidzoo on Twitter

Essenar, you say it shows a lack of foresight because apple didn't include hardware to allow for voice and data on verizon iPhone, but I think it's exactly the opposite. Why would they include additional hardware for something verizons network cannot support yet? This would increase their cost and decrease profit. And when the verizon network does support it, they can then sell everyone a new phone that does have the necessary hardware. To me, that shows plenty of foresight!!!

I'm on AT&T, and I don't really need voice+data. Either I'm on wifi or I just don't need to look stuff up on a phone call. Maybe its more important to others :/
I wouldn't miss it though if I didn't have the option. I'd just hang up and call them back if I had to lol.

If they included LTE, people wouldn't say things like, "Should I wait for LTE devices before deciding?"
They would just buy the iPhone 4 and not even think about the Bionic or Thunderbolt.
I'm one of those people. I'm not jumping ship until I see an official release date for Bionic along with a review. That's one customer they have waiting on the sidelines.
Would it add to cost? Sure, but it would also definitely add to revenue because people will love knowing that Apple took charge ahead of the change.

@jelionking you should not offer an explanation on technology you do not Understand. Your response is riddled with inaccurate information.
The most blatant perhaps is that LTE will carry the data and CDMA the voice. LTE will totally replace CDMA and carry both voice and data simultaneously. AT&T is also moving to LTE.
