I've heard that the sleep/wake function does not work for many third party cases. I currently have a STM Skinny for the new iPad on preorder on radtech. Does anyone have it yet? I know some eBay sellers are already selling it (in stock). I do not want to have to return them since shipping is so expensive to Aussie... I know the Incipio Lexington advertised that it works, but in reality it doesn't. This worries me quite a bit.
