Re: "...even on AT&T and T-Mobile the iPhone cannot do simultaneous voice and 4G LTE data."
"...The iPhone switches to 3G data when simultaneous voice and data is needed because there are not separate antennas for the 4G LTE radio and the voice radio.
Apple did not want to add the expense of a second antenna which would allow the LTE radio to have it's own antenna rather than sharing the antenna between the GSM/CDMA radios and the LTE radio."
thats incorrect only the all AT&T iphone can do simultaneous voice and data even the iphone 5, AT&T struck a deal with apple to only allow there Iphone to do it so they could stand out(example: sprint unlimited data iphone, Verizon iphone with the most LTE coverage) I dont know if the T-mobile one can but that launched over 6months after the rest so it didnt realy matter
