Apple will use Samsung component on A7 Chip?
It is now past that, Apple's A6 and A6X chips were made by Samsung. Also it is rumored that A7 chips would not be any different and will use Samsung's component

A7 chips are rumored to be use in iPhone 5 and future iPads.
NOTE: A news was rumored in June this year for all future chips Apple reached a deal with Taiwan Semiconductor Manufacturing Company. If that's the case why Apple is taking the risk?
However is it possible that Samsung may ask Apple not to use their components and can cause worries to Apple's near future plans?
