I've been waiting, watching, hoping for one. I originally had the Case-Mate leather holster for my 3G and 3GS, but it wore out. I replaced it with an iSkin Revo plus RevoClip. I then upgraded to a Revo2 and RevoClip2. Unfortunately, Case-Mate's Combo http://www.case-mate.com/iPhone-4-Cases/Case-Mate-iPhone-4-Carbon-Fiber-Case-Holster-Combo.asp still isn't available. ISkin hasn't announced their availability for their I4 products yet. So, I bought a cheap silicone case from HHI and slipped it on - functional, but loose fit. However, I slipped it into my RevoClip and realized that it fit really well - in fact, better than the Revo2 case. Given that I love my Belkin Grip Vue for my iPad - I went and grabbed the Vue for iPhone 4 at Best Buy - and it slides nicely in and out of the RevoClip2. http://www.belkin.com/IWCatProductPage.process?Product_Id=512159 http://www.iskin.com/store/i2shop_revo2.tpl I love the combo!
