I was wondering whats Att hspa+(LTE) backhaul. I havent found anything to help me get out of this confusion, but i have read that with AT&T new LTE network they will increase there HSPA+ backhaul, when LTE is in your area. I know the Atrix is most likely not going to have LTE. But does increased backhaul mean better or more consistant hspa+ speeds. One more question: Can the Atrix be upgraded to cat. 14 (to 21mbps download speeds) Sry if it is confusing, but i really dont know how to put it in other words. Can anyone help me?
