It really surprised me just how difficult the Nokia N97 back cover was to remove, almost as difficult as the iPhone and that's not meant to come off!. When I first took the N97 out of the box and had to remove the back cover, I was quite concerned the cover was going to snap in two, so it took me about 5 minutes to get it off.
In the end I used my nail in the groove in the back cover, held my breath and give it a good firm yank. And ta-da the cover was off.
Anyway, because of the difficulty we had, we've made this quick demo to help those of you still struggling with the cover and hopefully lay any concerns to rest, it really is quite durable and I'm pretty sure you won't break it, if you follow the instructions in the video.
