A Deutsche Bank analyst, Kai Korschelt, has devised a more precise estimate of how much a new patent deal with Nokia may cost Apple. Korschelt's numbers assume a 1 percent royalty on all iPhones sold through the first quarter, which is in excess of 110 million units; they also assume an average selling price of $550. With that considered, Apple's initial lump-sum payment could be worth €420 million, or about $608 million US.
