I just wanted to say thanks for this thread. Especially the picture of the foam donuts that (I assume) indicate the new no-echo version and the comments that one ordered recently from Amazon had those donuts. I had watched several YouTube reviews but this thread pushed me over the edge.
I got mine today (black from Amazon) and it has both the foam donuts and the paper over the holes. Coming from a ruggedized flip phone, the Otterbox makes me much more comfortable with my iPhone. It is much easier to hold (these things are really slippery without a case, already dropped it once earlier in the week when trying to put it back in my pocket) and I'm not worried about destroying it anymore.
I'm a photojournalist so I'm running around everyday and never know where I'll end up: could be anything from a simple portrait in the studio to a petro-chemical plant fire. My stress level about the iPhone dropped significantly after I strapped it into the Otterbox.
At the moment it is on with only the built-in screen protector and the "oil slick" issue is starting to bug me. I'll be anxious to hear if the Power Support anti-glare (or Crystal) fix the issue. I'm really hoping I won't have to resort to the "cut out the built-in protector" method mentioned earlier in this thread.
Again that black over white looks really nice. Gives it just a splash of contrast and personality without being super bright like the all white or pink. I'm a little worried that if I ever drop my black one I'll have trouble finding it, especially at night. That alone would have made me seriously consider the yellow model if it would have been in stock at Amazon. Personally if I were Otterbox I'd consider offering mix-n-match colors on their website.
