I just got my 8100 2 weeks ago and immediately fell in love with it (how could you not?). I was so careful with it, cleaned it, wiped it, kept it spotless. And then after 1 week, for the first time in my life (I've had cell phones for over 6 years), I DROPPED it! On hard kitchen tile flooring. The sound it made when it hit the tiles sounded like a hammer ramming into it at full force. I literally screamed when I heard it.
The aftermath? Not even a scratch, no joke. I was absolutely shocked because it sounded like it should have split in half. It is in the same condition now that it was when I pulled it out of the box.
However, the funniest thing is that now I am getting better reception and call quality than I was before. I'm getting 5 bars in places I used to get 2-3 and people arent breaking up at all anymore. Also my friends tell me that I sound much clearer on it and thought I might have gotten a new headset or even a new phone. The difference I'm hearing on my end is also substantial and very easily noticeable. I'm in shock.
So, moral of the story. If you drop your 8100, don't assume its the end of the world. Good things can come of it too
