Ridiculous CDMA iPhone firmware delay theory

    Okay, so we all know that the CDMA version of the iPhone 4 has only received the minor 4.2.6 update after shipping with 4.2.5. Since then the GSM model has received the 4.3 update and the 4.3.1 update, while the CDMA version remains where it was nearly 6 weeks ago.

    So, I've read some people claiming that the reason for the delay or lack of update for the CDMA iPhone is because Apple is waiting on a firmware update from Qualcomm for the MDM6600 chip. Okay, I could understand that. Then the past few days I've read reviews about the HTC Thunderbolt for Verizon, which is the first Verizon phone that does simultaneous voice and data over not only LTE, but over EVDO as well. This got me to thinking. Could it be that this update Apple is waiting on from Qualcomm could be a firmware update that allows the iPhone 4 to handle simultaneous voice and data? I've done some research and no one really seems to know for sure whether or not the MDM6600 could be upgraded though firmware to be able to do this.

    I think if this is what's going on, it's a pretty decent reason for Apple to be holding off on updating the CDMA iPhone 4.

    What do you guys think, am I crazy or is this a valid theory?

    That would be nice. It's kind of annoying that Apple never mentioned 4.3 for the CDMA phone. I kind of doubt that's the reason but we shall see.

    Wouldn't this need a hardware upgrade also?
    I don't think it's just software.

    No one seems to know for sure since the exact capabilities of the Qualcomm chip in the CDMA iPhone don't seem to be known.

    I don't know but I think they would have enabled it if they could.
    So they don't let AT&T attack them with ads about no voice and data etc...

    The way Verizon's network is set up, you're not going to get simultaneous voice and data period. Maybe if there were two independent RF receive chains in the phone it could be done. Except I don't think the single MSM6600 supports that. You'll have to wait for LTE support for V+D.

    your first sentence is plainly incorrect and even debunked on your own with your next statement.

    the current solution was supposed to be an extension of the EVDO standard in Revision B. VzW's network is capable of being software upgraded to the RevB standard and allow for simultaneous voice and data and/or the baseband can be made capable of the same function by using a MIMO type setup.

    the question is if the current 6600 baseband is capable of MIMO to allow simultaneous voice and data without the network undergoing a RevB upgrade.

    to further discredit your comment is the fact that the HTC Thunderbolt is capable of simultaneous voice and data over EVDO without the RevB network upgrade.

    Why would this require Apple to hold off updating their OS?

    let's use "Occam's Razor"....could it simply be that 4.3 only added personal hotspot to GSM iPhones? and the Verizon iPhone shipped with this feature so no need for an update?

    Beats me, haha. Perhaps they want to match up the versions on both GSM and CDMA models, and so they will roll this out with the 4.3.1 or whatever it is at the time they're ready, rather than being in the situation they got into with the release of the CDMA with a 4.2.5 and 4.2.6 which never existed for the GSM model.

    4.3 only really updated adding personal hot spots which verizon already came with 4.3.1 was just to tweak some bugs in 4.3

    OP what is in the GSM update that you wanted?

    Below are the updates available in 4.3. I think 4.3.1 was just some bug fixes from 4.3. Also, I'm not sure how many of the bug fixes in 4.3 were actually addressed in 4.2.6, but personal hotpot is certainly not the only difference between 4.2.6 and 4.3. The new Nitro JavaScript engine is sort of a bit deal also. Straight from Apple about what's in 4.3...

    Mostly the new Nitro JavaScript engine, which speeds up Safari drastically. Also Home Sharing and AirPlay for third party apps.

    I just find it funny about all the fragmentation talk of Android and this is exactly just that.

    I remember a few apps had to update or fix things because of the Verizon version of the phone. If there was not fragmentation why would this occur?

    Which is exactly why I'm hoping there's a good reason for this to be happening, like Apple waiting on this update from Qualcomm. It's probably just me being hopeful, but oh well.

    newsflash my friend...it did not speed up Safari all that drastically...and are there even any third party apps using airplay yet?

    thats not really the point.

    Although i believe 4.2.6 safari version was already some what "snappier" which would explain why when AT&T would reach speeds of 3-4mbps and the Verizon model would only reach speeds of 1.4mbps yet both would load web pages at virtually the same time.
