I think the answer is "duh", but that's not likely to stop Apple. The patent situation is a Mutually Assured Destruction scenario. Nokia could likely sue Apple and get an injunction granted on the sale of iPhones. This would be devastating for Apple, but Apple could just as easily sue Nokia, and that would be equally devastating. Neither company can afford the risk of getting an injunction granted on their products, and both companies know this.
