Apple, being an arrogant underdog, will underestimate Nokia's capacity for hiding knives on its person. Apple will then have to react quickly and catch each knife within his own weapon of choice, the Red Delicious.
After the Finnish opponent is adequately disarmed, apple will throw the fruit with knives over the edge of the bridge they're on. Then it's up to an American fruit versus a Finnish maniac.
Blows are exchanged, both suffer broken noses and bruised cheekbones, black eyes, and chipped teeth. Then Apple picks up a loose piece of pavement from a nearby pothole (Because American roads are trash nowadays) and brains Nokia a few times, causing massive hemorrhaging within Nokia's head and effectively killing him.
Then in the murder trial Apple will be acquitted because he bought out everyone in the courtroom with his mountainous piles of cash.
He'll then go on to attempt to take down bigger fish, and eventually bite off more he can chew, and get himself a permanent dirtnap from Microsoft, whom not only has a host of bodyguards and high-caliber weapons, but also ingenious ways to dispose of a body.
