Robert,
FYI, you may want to edit that LTE bars post for the Optimus G. The keystroke sequence is the same for the Opitmus G as the EVO,Viper,PHOTON Q.
And apparently the Optimus G's 4g icon applies to data and not just voice (like the iPhone5). (The manual says the icon is for data also).
Again, all this is prefaced by being a "NOOB". (legal disclaimer for anything I post could be total nonsense and I cannot be sued or held accountable for it.)
