German site Apfelpage reports that Apple has installed new display cabinets outside of its new, yet-to-be-opened Berlin store. The displays currently promote the iPhone 5, with mock, over-sized iPhones not uncommon to other Apple retail stores.
It's understood that the move will attract customers to the store as there is not much else besides two small Apple logs mounted on the store front to attract potential customers. However, Apple Stores, particularly rode side ones, are well known for having minimalist, sometimes understated fronts. Both the Regent Street and Covent Garden Apples stores in London come to mind.
