Verizon says simultaneous voice and data coming

Verizon late Friday indirectly confirmed some of the rumors swirling around the CDMA iPhone's ability to handle simultaneous voice and data. Executive Brian Higgins mentioned that the company was working on a way of overcoming CDMA's inherent limit on data, which prevents the EVDO 3G conection from running at the same time. He didn't give the WSJ a timetable for when it would be ready.

Although not mentioned by name, the technique would involve Voice over Revision A, or VoRA. The technique puts calls on EVDO Revision A alongside data and gives it behavior similar to HSPA 3G on a network like AT&T's or T-Mobile's. Some Verizon phones, such as the BlackBerry Tour or G'zOne Ravine, already use EVDO for push-to-talk calls.

The network adaptation is informally considered important to the iPhone's launch on Verizon early next year. AT&T's ability to support simultaneous data and voice on 3G has been a key selling point for the iPhone that has turned up in TV ads. VoRA would immediately close that gap and play to the iPhone's strength in multitasking during a call.

In the future, 3G will be a non-issue as the eventual adoption of LTE-based 4G will solve the technical issues. LTE doesn't have its voice standard finalized but will allow CDMA to work unimpeded and should also allow simultaneous voice over LTE when ready.

    but what about the phone and the contract

    none of these rumors have addressed the tech in the phone and the issue of two sets of models or not.

    Plus in 2008 there was a lawsuit that revealed that ATT has a contract until 2012. Nothing was said about buyouts etc. So oh rumor 'sources' how is Apple going to deal with that issue. Are they buying out the last year of the contract, is there some kind of minimum network quality clause that voids the contract, is ATT letting them off the hook or is there some kind of loophole like Verizon, T-Mobile etc can have the 3gs but not the latest phone.

    Without these kinds of missing details, the rumors lose some impact and just come off like the same old same old.

    And here we go again with the monopolistic activity rumors. They should shut this site down for supporting monopolistic activity.

    Re: but what about the phone and the contract

    "none of these rumors have addressed the tech in the phone and the issue of two sets of models or not."

    Really? I've seen a number of rumors mentioning a CMDA-only iPhone4 in parallel to the current GSM-only model. I'd love to see a dual CDMA/GSM (or CDMA/LTE capable) phone, but the wind doesn't seem to be blowing that way.

    From what I've read, the New York Times and the Wall Street Journal are getting information from people inside Apple and/or Verizon. This is NOT some-random-site repeating information from "analysts" who are repeating things they read on rumor sites.

    There were some rumblings a while back that ATT may have traded something for the last year of the contract, or yes, perhaps they have failed some performance clause (who knows, maybe even something attached to market share that has been triggered by Android's rise on the scene). The preponderance of evidence really seems to be falling into place for CDMA-only iPhone4, on Verizon, at the start of 2011.

    No, there's no proof yet [that's why they're called rumors :)], but I think this time it's real. We'll know for certain, one way or the other, in a couple months. I'm very interested to see how it plays out, but it's not worth arguing about.

    Dual tech...

    Apple is still facing backorders for iPhone 4 worldwide, having 2 product streams would put a serious dent in over all distribution capacity. The only way forward that makes sense is a dual tech phone. This means the steel antenna and guts are pretty much the same, save the updated chip(s). Having 2 different iPods for Mac & win only made sense for a very short while, at which point a universal model was released. Imagine the confusion if there were network interoperability limitations.
