I've bought a normal black blackberry 8520, and I've seen on ebay a purple full housing case for my blackberry! But its from hong kong, and I'm just worried that, if I get it, that I can't actually take the original black case off to get the new purple on one! (if that makes any sense?!)

Is there certain tools you need or can you literally just pull the original case right off the blackberry?

Here's the case on ebay :

(its a really nice case)

Hope someone can help!
Thanks!
