I have an old 3gs which works fine, but the volume rocker button fell off and is lost. They are sold online quite cheap. But even on Ifixit.com, they don't show how to replace this button. Does it just get glued back on? Is it part of a larger component on the inside of the device? I was just wondering if anyone has any experience with doing this type of repair. I can send it in to one of the many 3rd party repair companies, but if all they will do is use crazy glue, then I can do that myself.
