Question about simultaneous voice+data (ATTN PALM PRE USERS)

This might be a dumb question but here we go. IF the iPhone comes to Verizon, since their network doesn't support simultaneous voice+data, does that mean if i'm in safari or in the app store and someone calls me it'll go straight to voicemail? Or will it just disconnect me from the internet momentarily to receive the call? If it's the former, that's a pretty HUGE downside to a verizon iPhone.
Palm Pre users would have this same issue right? Any Pre users here to shed some light?
 
I asked the same thing when inquiring about the Storm2. I was informed that it would interrupt your data, and you would still get your call.
 
Ah, thank you both. That's not so bad. I'm still debating whether I'd switch to at&t or stick with verizon.
AT&T = faster downloads, simultaneous voice and data, less coverage, saturated and unreliable networks

Verizon = slower downloads, no simul voice+data, better coverage, more reliable

Sigh.
 
When you're on EVDO, voice connections have priority.

Any data connection is paused, and you are given the choice of answering the voice call or not. If you do take the call, then when you hang up the voice call, the data connection resumes.

For example, if you're watching Sling over 3G (something Verizon allows) or streaming Pandora, they pause while you take the call, then automatically start again when you hang up.

The nice thing is that you don't have to restart an app just because you took a call. The downside is that you can't use the network while you're talking.*

(*) Unless you use a VoIP app like Skype. Or are connected to WiFi.
 
When I was on the 2G it would always go to voicemail, but I guess from the responses, Verizon handles it differently.
 
If it interrupts your data, then I'm fine with that. AT&T just sends calls straight to voicemail if you're on edge (which I am quite often since my area doesn't have 3g yet)

Yes. Everyone talks about how you can't use voice and data on Verizon or Sprint and how its a terrible thing. MOST people very rarely use this anyways. If your accessing data and a call comes through then you will still receive the call on Verizon/Sprint. This is NOT the case with AT&T. If you are on Edge and using data, your call will go straight to voicemail. This isn't a huge problem for me since I live in a 3G area, but it is a problem when I'm driving on long trips. I've had more calls go straight to voicemail while streaming Pandora or checking email then I have ever used data while in a call, so I'd say that this is a win for Verizon/Sprint.

That has nothing to do with a CDMA or GSM standard, its a software issue and it varies by phone model and manufacturer.

Definatelly not a win for CDMA.

If the number of times that I have not received calls because of accessing data on Edge exceeds the number of times I've actually used data and the phone at the same time on 3G, how is this not a win for CDMA? It might not be for you, but for me it is.
 
Its called a CDMA limitation.
What you're referring to is an Edge limitation but if you're on 3G you dont have to worry about that. You dont see AT&T advertising that feature for their 2G service cause its the same way internationally.

Moving past this point...

Do you know how the LTE network will behave? I'm assuming that it will allow voice + data, but I don't remember ever hearing anything confirming or denying this.
 
LTE will be data only, Verizon plans to use their existing 1X for voice for some time. I remember reading somewhere they where planning to use it up until 2016.

I don't even think there is a voice standard for LTE yet.

LTE is designed from the ground up to use IP packets as the fundamental transport for all communication between the phone and the cell tower. Therefore, aside from operating two parallel networks (one LTE network for data, and one legacy network for voice), a pure LTE network that offers native voice connectivity will unavoidably involve some form of VoIP.

The open question is whether the networks adopt a solution that is based on existing VoIP products, or if they'll use something new. The 3GPP is advocating IMS, which builds upon SIP.

Good point.
Will they switch completelly to a voip type of of solution or keep the existing 3G/2G setup for voice and LTE for data only?
I think they should go full LTE for both voice and data like the cable/phone companys are doing for home phone service.
