That guideline, as you put it, is Apple's official statement of what features are supported on which networks.
There is nothing more that can be added here. Apple's statement is final as far as these forums are concerned.
If you believe that the law should enter into it, then contact a lawyer. ANY discussion on those lines is forbidden by the TOS. Or haven't you figured that out after having multiple posts deleted by the hosts for threatening legal action?
Maybe you should try reading the standards documents some time. LTE does not necessarily = LTE.
Did Apple advertise that the phone would work with YOUR network? No... As a matter of fact, they did not. YOU chose to ASSUME that it would work.
I'll say it again. If the TOS for these forums are unacceptable to you, then go elsewhere.
