It seems to depend on which rep you talk to as to which variant they say they have. My e-mail yesterday from Jenny said she had checked with the warehouse and it was the 984. My understanding (and please correct me if I'm wrong) is that the 983 is most likely AT&T and takes power mat uses LTE bands 2,4 17; the 985 probably TMobile and takes Qi and uses LTE bands 2 and 4; and the 984 takes Qi but only has LTE band 7, and possibly headed to Canada where Bell and Rodgers use LTE bands 4 & 7.
All in all, I think I will just wait and see.
