It's too late for this to be an April Fools joke, so I'm assuming this $5000 Caviar Vladimir Tsarphone, which runs a Nokia OS from 2008, is real.
From the marketing copy:
Flawless. If one characterizes this phone with one word, this very epithet should be definitely chosen. Concentrated masculinity dressed in a strict “smoking” of the most classic style. Confident and expressive tandem of shining gold and the ultimately black color attracts eyes and places a focus on the original shape – six charismatic tops give the dynamics and some belligerence to the phone’s silhouette, because it starts looking like a sword.
Called with the name “Vladimir”, according to the creators’ idea, it refers to the image of Prince Vladimir Krasnoye Solnyshko (the Red Sun) and symbolizes fair power, union and wisdom.
Strict, business but along with it festive in its superiority and majesty, this phone is created for the most important talks of the most high-powered people.
