I've been wanting to replace my cover housing for a while. I've looked around quite a bit, and have found several sources that will provide the back cover housing and the chrome bezel. I've also found posts where people state that certain videos on youtube shows one exactly how to do this, but apart from finding videos that show how to replace the screen, etc.., I couldn't find a specific video. I understand that this may well void one's warranty, but if I really wanted to have my iPhone checked out by Apple, I could well put my original housing cover back on. I've never had to take my iPhone into Apple, because all my questions have already been answered by previous posts from the good folks here at macrumors. Questions.. Are there any videos? Has anyone here at macrumors attempted this? How long does it take? Is it worth it? Thx.
