    GSM model A1428*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 4 and 17)

    GSM model A1429*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5)

    Which of these 2 will work on tmobile 4g? I just wanted to make sure which one to buy coz I'll be paying full price and I don't want to make a mistake on this one.

    Get the A1428.. The use of A1429 is for CDMA.

    T-mobile 4G is just HSPA+ if I am not mistaken. So either of the GSM models should work fine (once T-mobile completely moves over to the same frequency used by ATT for HSPA+). Only the LTE is different between the two GSM versions to differentiate between LTE used by ATT and LET used in other parts of the world.

    Both of these do not work with T-Mobile 4g. Until the refarm is complete you will not see 3G/4G speeds on the iPhone.

    You think so? But, it shows it supports the T-Mobile HSPDA Band.

    T-Mobile is right now moving its 3G network so that the iPhone can use its 3G service. Some areas have it already but tis not 100%.
