The iRetrophone Skyliner, designed by artist Scott Freeland, is a retro-style iPhone dock (compatible with 3G, 3GS, and iPhone 4) within a custom-designed, old-style desktop telephone. The iPhone connects via a standard connector within the dock, providing charging power and a working handset -- yes, the handset works.
Combine this dock with the aptly-named iRetroPhone iPhone app, and your iPhone retro-izing is complete. But for $250? They lost me there.
