As the other person said, you must be kidding if you think Apple worked with Nokia.
Did you read any of the posts that have been flying by?
WebKit was a project shrouded in almost total secrecy until it's announcement as Safari and was clearly done at Apple and based on KTHML/KJS.
Not only that, what would make the mobile version "special" (besides dealing with touch input and screen resolution)? Don't you remember Jobs' comments about it being the "full" internet?
Going further, why on Earth would Apple even hint to Nokia that they were working on the iPhone?
