Mobile hardware engineering chief's exit may not have been solely related to iPhone 4 antenna issues. A report says it was due to his failure to thrive in Apple's corporate culture.
The executive Apple fought IBM for just over a year ago leaves Apple in the wake of the iPhone 4 antenna mess.
A judge has granted IBM's request for an injunction preventing former executive Mark Papermaster from joining Apple as its new head of iPhone development.
New iPhone chief Mark Papermaster won't be using his chip development skills at Apple, having been chosen for a completely new role based on his leadership ability.
Apple's new iPhone hardware chief has now started working for the company, just as Apple beefs up its chip design expertise with another hire.
Apple says Mark Papermaster is free to join the company after settling a dispute over a noncompete agreement with his former employer, IBM.
According to court documents, lawyers for Papermaster plan to claim that Big Blue's noncompete agreement is too broad and shouldn't apply to a consumer electronics company.
It seems Apple has responded to the court wrangling over former IBM executive Mark Papermaster, who accepted a job running Apple's iPhone group last month.
Judge issuing preliminary injunction preventing Mark Papermaster from working at Apple believes the companies have competing chip businesses. Both work on chips, but it's not that simple.
IBM's lawsuit against former executive Mark Papermaster, who is trying to join Apple, underscores how companies can enforce restrictions on their employees.
