Update 11/2/14 - I just received the aluminum ring home button stickers and was able to get just the silver outer ring part out easily and put it on my phone around the home button. It fits perfectly! And I can still use TouchID just fine.
The stickers are on the right. You can see the one I removed the silver outer ring part from... and the other one with everything in tact. It was very easy to remove just the outer silver part... it basically came right off and still had some adhesive on it. We'll see how this holds up over the long-run with extensive use of the home button. It may lose some of the adhesiveness and fall off but for now, it seems pretty well in tact.
Best 99 cents I've ever spent (I bought a few just in case I messed it up haha)
