Answer to "How do I fix or replace a broken ring/silent switch?"I've actually had this problem before. I dropped my iPhone 3GS the first week I got it (actually it fell out of my jacket pocket). The switch felt a little sticky, but it still moved both ways. Of course I was mad I had already broken an important feature as the ringer volume doesn't go all the way down otherwise. Oddly enough about 3 months later, I was showing someone that my silent feature was broken and to my surprise, it worked! I've always wondered what stopped it from working and eventually fixed itself. Judging by "forum"'s answer it sounds like my connector was loose, too. It must have been just loose enough to not work, but still be able to slide back into place eventually.
