    I am wondering if the iPhone 6 will support the above technologies! I understand the iPhone 5s or Iphone 5 did not....:mad:

    Unlikely. There's a whole thread about this already on MacRumors detailing why.

    VoLTE will be here before you know it. I wouldn't be too concerned about it at this point.

    Yes, VoLTE is being rolled out for Verizon before the end of September, so yes, you'll be able to "talk and surf" at the same time.

    It is a technology limitation, not a phone limitation.

    Yes, but:

    Not happening. Apple isn't going to modify their hardware just to accommodate 2 carriers that form such a small portion of their overall user base. Glad I'm on a GSM network.

    Well....I guess I should be happy that my 40 a month account (SERO-P) has unlimited LTE,3G, 1X so I will just try to make FaceTime voice calls when I can...

    That is ludicrous. Way to go, Verizon :rolleyes:

    CDMA is fairly popular in the USA thanks to Verizon and Sprint, but worldwide, GSM is king.

    Yes the whole world uses GSM. Do you think the 150m or so customers that sprint/verizon have are significant compared to all other GSM providers?

    I understand that, however, Verizon is a huge carrier. You may be right, that percentage wise it's a small number...

    No, I don't, and I understand that GSM is "superior"

    There are ways of supporting voice and data on CDMA carriers, and quite a few of today's (LTE) smartphones already do it, just not the iPhone.

    Which is frustrating for those that are on CDMA carriers and want the capability when wifi isn't available. Personally I don't need it. I turn wifi off when I'm calling people :p

    Well, yeah, not possible with the iPhone (at least not so far).

    Why turn off WiFi when calling people though?

    Yes there are ways to support voice and data on CDMA carriers. The iPhone has never supported it yet. With VoLTE about to be released, I doubt Apple will be supporting it in favor of VoLTE. Apple is big on embracing new tech, such as USB, etc.

    It's both, actually. CDMA data networks (i.e. EVDO) can't be used when a cellular call is taking place. However, with LTE, which is GSM based, you can.

    Plenty of phones on Verizon and Sprint can use simultaneous data and talk while on LTE. I do it on my S4. The reason they can is because the CDMA and LTE radios are split.

    The iPhone can't so simultaneous data and talk on CDMA/LTE because they use a single radio design.

    Apple could easily just split their radios, or just wait for widespread VoLTE, with the latter being the obvious choice.

    CDMA can support it itself too without LTE if SVDO or EVDV is deployed and used.

    Correct. This requires an additional antenna which the newer Android phones have but Apple has opted to not add to the iPhone. Definitely Apple's choice at this point.

    Love my iPhone but I hate getting calls on it as I'm always using it as a hotspot.
