I have proven Kevin wrong!! :)
A while ago our commander and chief left a rather helpful blog post for those of us who want to put a case on our 99xx and still have a holster to fit with it and get all the holster perks. The post can be found here:
BlackBerry Case Tip: BlackBerry Bold 9000 Leather Holster works with the Bold 9930 / 9900 Hard and Soft Shell Case! | CrackBerry.com
Note that he said the koskin holster doesnt fit, only the leather holster fits. I didnt see that because after reading the first sentence or two I sprung into action. I did buy his hard shell but hit ebay for a 9000 holster cuz it was cheap. Turns out it was the koskin, I read the rest of his blog post later after everything was shipping and almost ordered another holster! After it came in I tried it out and it works just fine. So kevin, your great, but you are wrong. Ill give ya a break because as far as heads of state go thats a rather small mistake on your part. Below are some pics.
