Foxconn has a very direct impact on Apple's product, so any issues with quality would come back to them pretty quickly. Foxconn also has an ongoing partnership which I would expect to be worth a lot of money to them.

On the other hand, everything I've seen so far outsourced in IT in a standard way could come back in any condition. Worst case, it's unusable, but contractors get paid anyway and move to the next client.
