Thing is, there aren't many ideas Samsung can steal from Apple by looking at their current hardware set. Their processors are both tweaks upon the same basic ARM designs, and really, Samsung is moving in an entirely different direction than Apple on this front.
And what about screens, ram, NAND chips, ect.? What can they learn from that? That the iPhone 6 will have a high quality 4.5 inch screen and 2GB ram with 32GB minimum storage? None of these are directly designed by Apple, only utilized. All they'd get is a basic spec sheet, and it's not like Samsung doesn't already have products out that nearly match that now.
The only thing Samsung could conceivably steal from Apple and actually come out ahead would be their software and chassis designs. Neither of which they'll see at any point during the component manufacturing process.
