It's been more than a year since we've formally compiled iPhone 5 concept designs (see "Apple iPhoneys: The iPhone 5 edition") and with the number of new designs emerging in recent weeks that collection is looking badly outdated (though we did at least call attention to a curvaceous mockup making rounds in February).
I've done the rounds this week to cobble together a fresh collection built on rumors, speculation and artists' imagination, although I can tell you off the bat that the coolest design -- literally -- is an iPhone 5 knockoff being sold as an ice cream treat in China, where trademark rules are a bit different than in the United States (via Rocketnews24).
