That may be the case, I'm no expert, but from the little bit I've Googled, "phone" is for HSPA+ (4G) and "nxtgenphone" is/will be for Voice over LTE (VoLTE) whenever AT&T rolls that out. "Phone" definitely works, but the speeds are consistent with H/H+. All I know is that after running AT&T's own RUU, the only APN on my phone is "ATT nxtgenphone" and it works.
The settings are basically the same as "phone," Just give it a name like "ATT Nxtgenphone" and simply put "nxtgenphone" (w/out quotes) in the APN slot. I don't remember if "phone" had a setting for MMS protocol, but here it's WAP 2.0. APN type = default,fota,mms,supl,hipri
