    It will NOT be compatible with the LTE network.

    "The Verizon iPhone 4 will not support Verizon's 4G LTE network."

    Now that ATT Has 4G service, will the IPhone 4 receive 4G from ATT?
  • roaminggnome Level 10 Level 10
    No. It will not.

    The iPhone 5 might, but the iPhone 4 won't.

    Keep in mind that I said MIGHT. As the iPhone 5 isn't out yet, we have no idea what it will support.

    Att wont have LTE till then end of this year...and no it is not 4G...4g by its specs dont exist yet on any network

    .. don't take the bait on the 4G marketing hype.. unless you use your iPhone for data tethering with your Mac I do not think there's much of an advantage of "4G" on an iPhone.. the other post that discussed the LTE network not being 4G is correct. I think the issue for consideration should be the signal quality particularly if you are in a city with spotty AT&T coverage. I'm not too concerned about Verizon "coverage" though since I don't happen to need cell phone coverage in North Dakota and other environs

    Even if you buy a Verizon LTE iphone in the near future and you carry it into a non LTE area it will revert back to EVDO 2G. It is not backwards compatible.
    However, when AT&T launches LTE, it WILL be backwards compatible and just drop down to 3G.

    This is backwards compatible - with Verizon's CDMA network to Verizon's 3G or 2G network, whichever is available at the time. Verizon's so called 3G network is not available in 100% of their network coverage area.

    However, when AT&T launches LTE, it WILL be backwards compatible and just drop down to 3G.


    Correct, and the combination LTE/GSM iPhone will drop down to 3G, EDGE or GPRS, whichever is available at the time. AT&T and every GSM network provider throughout the world does not have 3G network access available in 100% of their coverage area.

    I wouldn't count on LTE being available for the iPhone for the next two generation models. Even if Apple released an iPhone LTE model, you would be going on 3G for a while before a stable LTE is released in your city.

    Verizon nor AT&T are fully deployed in LTE nor is WiMax Sprint. So it'll be a while before they have LTE coverage for the iPhone in your local area.

    If you review this link then select "4G" and refresh data, there's only 20 or so cities covered out of the countless number of cities in USA that has 3G.

    I live in New York City, 100% coverage here for LTE.

    Since LTE is GSM I wonder how quick it switches to CDMA when there is no LTE signal? Plus i guess having 2 radios CDMA and LTE will eat a lot of battery life... rather than just one radio for LTE if you already have a GSM network...
  • Allan Sampson Level 10 Level 10
    LTE is based on GSM but is not GSM.

    LTE will likely consume more battery than CDMA just as 3G consumes more battery than EDGE with GSM.

    The LTE iPhone for GSM networks will be a combination LTE/GSM iPhone just as the LTE iPhone for Verizon's CDMA network will be a combination LTE/CDMA iPhone. LTE and GSM are not the same.
