Hm, some interesting methods you guys go as far as protecting your blackberry.
I have had my Curve since February and the screen does NOT have any scratch on it except for it being slightly oily. It has almost always been in the FoneGear holster that I have here. I have only recently (since July 26th or so) used the Cellet red shell case to protect the Curve even further. (One thing of note: I do not have the belt clip attached to it, so it does look a little bit weird without it, but it's ok with me anyway.)
It goes in my FoneGear holster like a glove, except for the fact that the Velcro is a little bit annoying.
To purchase the Cellet Shell Case:

FoneGear Holster... just go to your NEAREST Walmart. They have it. They're cheap too! I wouldn't exactly recommend it but if you need fast, cheap and easily disposable holster, this is it! ;)
But Wait! There's nothing more to look at here... really!
