Hi. I just got my new Nokia 909 aka Lumia 1020 for at&t. If the device is supposed to utilize LTE for data, I don't yet see it. All I see in the upper left is "4G", not "LTE" or "AT&T LTE". What gives? Do I need to worry about adding an internet APN or mms APN? Please let me know, as I plan on going to the at&t retail store this afternoon to get a new LTE-capable SIM card. Thanks!
