I'm new to smartphones, bought the Droid about a week ago, got a couple of questions. 1. The lights on the 4 permanent menus on the bottom of the phone are going on and off randomly (quite frequently), is this normal? If not, any suggestions? 2. Is a task killer app really necessary? Seems to be some debate about this. If it is, which is the best one? 3. Are there certain apps that no self-respecting Droid owner should be without? What are a few of the "must haves"? 4. I downloaded the Astro file manager, but haven't figured out how to create new folders (remember, I said I'm new!) Can I get a quick tutorial. Got many more ?'s, but I'll let you guys handle these easy ones first. Thanks in advance!
