Back cover replacement needed?
If I am very careful, is it possible to get the back cover off intact?
I'm not sure you can be that careful. I've removed about four or five of them, and although I have had success putting them back on, they're never quite right again. There's not really a good way to get to the clips, and removing them tends to break them. If you get lucky and remove it without bending it significantly, and without breaking too many tabs, you can try to bend the tabs back into place and snap it back on when you're done.
