This one's for the radio/phone techs out there. How about a short course in LTE. I sort of understand the difference between CDMA and GSM. Where does LTE fit in? Is it an entirely different standard that requires another radio in the phone, or can a LTE radio also do CDMA or GSM? Does LTE carry both data and voice, or is voice still over the existing technology? Is all LTE created equal - will an LTE phone (Verizon Droid Bionic perhaps) be able to work on the eventual AT&T LTE network? Thanks
