ANDROID AND iOS DID NOT CREATED IT ( THEY STARTED AT ANDROID 2.2 "2.1 IF ROOTED" AND iOS 4.0 "3.0 IF JAILBREAK")

        GSM Association (GSMA) then reviewed by Federal Communications Commission (FCC)

        In the US, CDMA had been assigned the frequencies that GSM is running on the rest of the world.


        What network does LTE run on?

        It is based on the GSM/EDGE (GSM) and UMTS/HSPA (WCDMA) network technologies. So yes this was a trick question.
