The Vertu unit produced the Ascent Ferrari 60 phone to celebrate Ferrari's 60th anniversary.

"We worked very closely to develop this limited edition of 60 phones. Detailing on the phone is inspired by detailing on a number of Ferrari cars," said Vertu spokeswoman Elizabeth Maragh.

Nokia and other cellphone manufacturers are increasingly teaming up with designers. Earlier this week Italian designer Giorgio Armani joined forces with Samsung Electronics to design a television and a mobile phone.
