Just curious where did you get that explaination? I would be interested to see if there is any real truth to this. I know there are some Sprint employees that use this board that might be able to chime in???
As it has been stated, Sprint TV doesnt work. Maybe Telenav will, but maybe not. The setting you are referring to is the PCS Vision update. Anytime i am in a full bar area i do it because it updates my Vision profile, allowing for any updates to be installed to my q.
