I just recently purchased the iPhone 3g 8gb model, coming over from the palm pre(i am much happier i might add). I went through about four pre's because the speakers just seemed to blow out after about a week's time. It wasnt until i did some investigation and found out my work was the culprit. I'm a welder and metal grinder and lots of tiny metal fragments fly by my head daily and those fragments seemed to get into the speaker of the pre and blow it out. I was just wondering if anyone has any background knowledge about this for the iphone because if i could avoid blowing out my iphone speaker i would like to! I'm sorry if this has already been posted but to my best efforts i could not find anything about this problem.
