I haven't opened it (don't know how), it hasn't been dropped ever, never gotten wet. What is sbf? I am not sure how to do that and not sure about rooting. I have copied folders from the phone to my home computer, but not done anything other than the standard back up assistant thing. I am really a novice at this and this is my first phone ever. I got it for the data package as I rarely use it for voice and never for texts.
