The Sanyo RL7300 also switches from sprint only mode to automatic after using it a few weeks. does this on the reboot on every once and a while and stays there. It has the same software and hardware as the RL 4920 which also does the same thing. It is a systemic problem apparently in Sanyo phones with software 1.006SP and hardware 0201 I don't know if this is done on purpose or not.
