I've had the Hero since 10-29-09 and the scroll-ball light is always on, it never shuts off ... It's driving me CRAZY. Also; the light pulses very lightly. Like it has a short or something. I've checked all my messages, settings and I can't find the problem. Has anyone had this problem? How did you fix it? I don't really want to go to my local Sprint store because I'm sure they have no idea. Thanks!
