I found this on the Blackberry website under Accessories. It looks pretty cool and might solve a lot of peoples battery cover issues when its available.
I wonder if they will have it in Verizon's Dark Metal Color also!!!!!!
From the site:
"These BlackBerry� Battery Doors offer a personalized edge to your BlackBerry� smartphone. You can replace the original battery cover with a matching color or add one that is designed to add some personal style."
The Telus/Sprint/Bell Tours don't have that rubber matte and I'm hoping it will be available for purchase. I did like the matte back on my HTC Touch Diamond and gave a much better grip than the glossy back. More resistant to scratches and fingerprints too.
