!!! I dont know what to say!. I really hope iFixit didnt get something wrong..but from the pics and the model number they seem to be right!. What is going on? a 7 band LTE chip which is not turned on?? Recent news...Google supposedly in talks with Dish Network to be a phone carrier. Are these two related?....maybe When Tmobile has their LTE towers ready this will be turned on?? I dont even... Edited to add Anadtech Review also mentions this part, so yes, this part exists OMG Basedband 4 is exactly the same LTE band Tmobile is installing now!!!!
