Although I don't know about this leather stand, the "leather" battery door (if ordered from truesupplier or ebay) is total crap. Don't waste your $$$. It's not real leather, and is a cheap Chinese knock off that feels low quality compared to the rest of the 9900/9930. I ended up not even using it the same day I got it, total crap.
And I am going to take the cover off and rest my phone on 2 Chinese plastic clips with one hand.
Post me a video of you doing that, and I will post you one of me putting my White 9900 with its case still on in a leather stand with one hand while scrolling my Playbook with the other.
Phill get a grip that is some dumbo's idea of a joke!
The backdoor is not a very bright solution if you are on the move and use your hardware as much as I like to do.
I've had the BB leather stand since my 8300. It fits the 97xx in Commuter perfectly, but it's a shade narrow for the 99xx in Commuter. The convenience key makes you have to angle it a tad to slide it in, but it holds it solidly. It'll fit a skinned or nekkid 99xx just dandily. Mine is currently at home holding my kids' 9860 (in Commuter).
The stand folds flat for easy storage and portability, holds itself together with a decent magnet, and has handy cutouts for convenient USB cable routing.
