Meanwhile on a serious note, I'm not getting the high and mighty thing. No one has suggested anything underhanded or deceitful, like; run over it with your car, say it was stolen, or any multitude of other less honest things. And the whole "We don't promote insurance fraud here at DF..." was so out of line that it's not funny. I don't believe the thread was titled "How can I get my phone replaced if I got it wet?" or anything. Posters need to slow down and pay closer attention to what is being said and not go off half cocked.
Anyway to the OP, I'm sorry to hear about your dust issue. Have you tried compressed air? There are some good brands that are really strong while there are some crap brands that will not blow out a match. I would go on-line and check some reviews then go to my local BB or OM and at least try one. I just wish I had some better advice since that's what these threads are about, not coming up with my own twisted sense of morality and criticizing something that's not even happening.
