I emailed their customer service to see if they'd have the Vapor Comp &/or Pro for the iPhone 5 and she said that she had no idea. Not exactly helpful, but I'd be surprised if they don't. I really hope they do. Since I got my first one (Vapor Comp Epiphany) several months ago, I've gotten several more and have used nothing else (and I am a total case whore who switches them up constantly.) I just use 'em with a skin on the back and my phone is still in pristine condition.
Oh, and no signal issues with either the Comp or the Pro. Never a waver.
