I just returned my first one x last night due to some camera issues, but other than that I had no problems with it. So, last night when I got the new one, I messed with the camera and some other functions just to make sure there wasn't anything obviously wrong with it before I left Radio Shack,and it seemed to check out. When I got home and was setting it up and I noticed that my home buttons were sometimes lit, and other times not....seemed to come on sometimes when I woke it up and other times not, even when I was doing several tasks that required using the home buttons. My question is: should the home buttons come on and stay on everytime the screen is on, and if they are not lighting up normally, is it petty to want to return this one as well? I'm thinking that if there is any small problem, then there may be an even bigger issue ready to show itself at a later date. When should the home buttons light up and when should they not?
