What did the Girl Scouts always say? Be prepared! (Did they always say that? Like I know.) Get your new iPhone 3G case before July 11 and be ready to slip it into something more comfortable right away (though I admit it, I'll be tempted to try to fit it into my 1.0 cases, just to see). There's always a ready group of accessories for a not-yet-released gadget, and you know what that means: lots of ugliness to sift through. I've done the sifting for you, so check out my picks for the best 3G cases!
