    According to the Apple site (http://www.apple.com/iphone-6s/specs/), there will be two models:

    Model A1633 (presumably AT&T and T mobile):
    LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 27, 28, 29, 30)
    TD-LTE (Bands 38, 39, 40, 41)
    TD-SCDMA 1900 (F), 2000 (A)
    UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
    GSM/EDGE (850, 900, 1800, 1900 MHz)

    A1688 (presumably Verizon ...and maybe Sprint?):
    LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 27, 28, 29)
    TD-LTE (Bands 38, 39, 40, 41)
    TD-SCDMA 1900 (F), 2000 (A)
    CDMA EV-DO Rev. A (800, 1700/2100, 1900, 2100 MHz)
    UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
    GSM/EDGE (850, 900, 1800, 1900 MHz)

    I'm a bit confused since this iphone 6s bands seem different from the iphone 6's T-mobile unlocked vs SIM-free. For comparison:
    iphone 6 model A1549 (unlocked T-mobile or AT&T and Verizon):
    LTE (Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29)
    CDMA EV-DO Rev. A and Rev. B (800, 1700/2100, 1900, 2100 MHz)
    UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
    GSM/EDGE (850, 900, 1800, 1900 MHz)

    SIM-free iphone 6 model A1586 (also Sprint):
    FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29)
    TD-LTE (Bands 38, 39, 40, 41)
    CDMA EV-DO Rev. A and Rev. B (800, 1700/2100, 1900, 2100 MHz)
    TD-SCDMA 1900 (F), 2000 (A)
    UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
    GSM/EDGE (850, 900, 1800, 1900 MHz)

    I was hoping that Apple would release SIM-free phone and to get one by mid Oct, but no. If that becomes available, if at all, it will either around Dec (before iphone 6) or early Jan next year (iphone 6). But maybe I don't need to wait and just get the full priced one and get it unlocked. I want one for mainly international use (i.e. most bands), but also use domestically (U.S). Does anybody know what LTE 30 and CDMA Rev A are used for?

    Comparing to the SIM-free iphone 6's bands, A1633 is missing CDMA Rev A & B but has LTE 30, while A1688 is missing CDMA Rev B. Correct me if I am wrong, but it looks like this CDMA Rev.A is for mainly older technology (3G). And most likely won't affect international use. So why buy A1688 at all? Can anybody tell me how not having CDMA Rev A would affect things to use domestically (U.S) and internationally?
