Wall Street Journal offers some additional information on the departure of Mark Papermaster, Apple's senior vice president for mobile devices. The paper suggests it's likely related to the iPhone 4's antenna problems, and also heard that Papermaster was "incompatible" with Apple's corporate cultural.
Exactly how much the problems with the iPhone 4 played in Mr. Papermaster's exit is unclear. The iPhone 4, a key device for Apple, has been beset by issues such as antenna reception and delayed production of a white version of the gadget. Several people familiar with Mr. Papermaster's situation said his departure was driven by a broader cultural incompatibility.
Mr. Papermaster had lost the confidence of Mr. Jobs months ago and hasn't been part of the decision-making process for some time, these people said. They added that Mr. Papermaster didn't appear to have the type of creative thinking expected at Apple and wasn't used to Apple's corporate culture, where even senior executives are expected to keep on top of the smallest details of their areas of responsibility and often have to handle many tasks directly, as opposed to delegating them.
