    I think I want a Bionic...but first I have a few questions related to the Tbolt:

    1. Will Tbolt be the only Verizon device ever capable of simultaneous voice and data?
    2. If so...WHY can't other 4G devices do it?
    3. Why is this not discussed more?

    Thanks in advance for help.

    Any 4G device has the possibility for voice and data. Idk why it's not talked about more.

    The difference between tbolt and all others is that it can do simultaneous data and voice over 3g as well

    Voice is a CDMA receiver and 4G data is GSM. You have 2 phones in 1.

    If Bionic and other 4G phones are capable...why is this not advertised more?? On Big Red's site, the Tbolt is only device listed as "simultaneous voice and data." This is what led me to believe it was the only one. I would think Big Red's marketing dept. would be jumping all over this. Can someone confirm Charge is able to surf and talk at same time.

    Yes, ANY Verizon 4G/LTE phone can do voice and data at the same time, as long as they have a 4G/LTE signal.

    They aren't advertising it because
    1. Not every market has 4G yet, so they don't want to sell a feature and have it not be accessible.
    2. The tbolt will do svdo on 3G only (and is the only one currently), but again, not every market is upgraded to enable it.

    I don't live in a 4G area, but can talk and surf on 3G on my bolt.

    Prediction: BIONIC will be the buggiest phone VZW has ever released. TBOLT is just now usable after a long while. I believe the voice/data at the same time is possible because of the presence of a SIM. Could be wrong, but I remember reading that somewhere.

    The tb runs on a a slightly different 3g network than all the other VZW phones called eHRPD. This type of cdma net allows simultaneous voice and data over 3g, but all the 4G phones will do it with LTE coverage. eHRPD is tied directly with LTE it was supposed to make the transition between networks smoother.

    3G Data & Voice simultaneous

    I myself can confirm this does indeed work, and quite well. I can make calls while hotspot tethered to the laptop, without dropping the data signal in or out of the laptop. I only get 3G at home for now.

    The reality is the Thunderbolt has two independent radios. Most other phones have one radio that supports one WWAN technology at a time.

    One TB radio is dedicated to 1x (voice) and the 2nd is DO (3G) or LTE (4G). It is simultaneous voice/data in that the 1x and data radios operate simultaneously on different frequencies.

    This is different than running voice/data over one radio such as sending voice and data down the LTE or DO pipe.

    The real reality is that you have no idea what you're taking about.

    You're right that there are two radios, But wrong about the configuration. The cdma radio handles 1x/EVDO, and the LTE radio is separate.

    During an SVDO session, both data and voice travel over the same connection. 1x voice + LTE, however, does use two separate connections - but is not unique to the thunderbolt.
