I see these as scripts that can be run on BB, but I haven't really seen anything that explains what the purpose of these are. I know that it sets the system so that it keeps 50, 75, or 100 mb of RAM free, but I am wondering what the purpose of this is? Also, what is the native setting? Does it help the battery life, or is it just for peace of mind. Is this something that should/could be used in place of an auto-task killer, or would these two things be completely different? Sorry for the noob question, but this is something I'm not terrible familiar with.
