So my dad heard about the JB update and asked me if he can actually be able to have a better time picking up the weak WiMax here since Sprint did some work to one of their towers and now its picked up by the phones (finally!) but was hoping with the new update that the radio is some how "stronger" [as he put it] so he can get better WiMax to his phone. So with that said, has anyone noticed a WiMax, 3G radio boost?
