In the very short time I worked for Era iPhone, we used to get loads of reports, at least 2 every 5 seconds and they would only be investigated if there was a PR online. I don't know why, but development staff don't really handle it. It's not because they can't, because they have the tools, but it's because that they are told (like I was) that it's best left to a PR. obviously me being me I investigated anyway but it's just development staff are told to stick with development and PR's are supposed to deal with it. I think it's a load of crap.
