If you haven't heard about the iPhone plus, it's for good reason: it doesn't exist -- at least not in physical terms yet. With Apple constantly being tight lipped about the various goings on of the company, it's rare that anybody other than the employees ever gets a glimpse at any product or concepts coming out. That's partially what makes the speculative concepts all the more fun.
Apple's iPhones over the years have barely changed. Slight tweaks to the designs here and there have left fans split. Some love the consistency, while others find the company boring. The Apple iPhone Plus concept is much sleeker, smoother and features a completely different feel in terms of direction and style.
