Really, I wouldn't care if cron didn't wake up the device. My goal is to write a script that helps me track a stolen nokia tablet every time it goes onto wifi. Eventually at some point, the thief *will* take it online, and when they do, I'll have their info. The catch is that the script needs to be set to run every xx number of minutes. Hence my preference to using cron. Although since there's no cron, alarmd will do.
