I dl'd Task killer because I was told it would automatically kill apps I'm not using so it doesn't max out my battery. My question is.....how do I know if it's running? I have these tiny icons on top of the screen now....they are so small I can't tell what they are...kind of look like something with a white check over it. ? How do I make sure it's working? Is downloading all I need to do? Also.....how do I usethe music that I dl'd from "Music Ringtone" for a ringtone? I can't find the songs on my phone. I looked under Music and it's not there. Oh...I have so many questions....but I DO love this phone!!
