I know, I know, it's been iPhone 4 case overload on GeekSugar — but there are just too many awesome cases worth posting about. My latest (and maybe even most favorite) find: The Little Black Book iPhone case ($40). The case disguises your iPhone as a little black book, secured by a hand-carved wooden frame and wrap-around strap. The inside of the case is lined in red, and it even features classic red bookmark detail, making it look even more like an adorable, pocket-sized notebook.
There's a version of this case for the iPhone 3GS, too, so even if you're not rocking a brand new iPhone 4, you can enjoy this sweet design. Fits perfectly with my love for all things Moleskine including the DODOcase for iPad.
