Yep, I got my replacement PLB last week (1st one was in a backpack that was stolen from my car). My WFR expired several years ago although I still retain the knowledge.
The biggest resource you have is your own knowledge and awareness of your surroundings. From what I read about Gerry, she had problems with way-finding in the first place and was not suited to hiking by herself because of that. Technology and maps and PSKs would have helped but are secondary resources; knowing how to find your way is so key to keeping yourself found.
