What If Samsung Stopped Supplying Parts For the iPhone 4?  This
is all hypothetical, but what would happen to the iPhone 4 if
Apple's vigorous legal campaign against Samsung caused an
irreparable rift between the two companies?  Several key
components of the iPhone 4 including the Flash Memory, DRAM
memory and applications processor come from Samsung. Together,
these account for $45.68 in parts which is 26% of the final
component cost of the iPhone 4.  If Samsung were to turn its
back on Apple, who would supply these components, how much would
they cost and how quickly could another company supply them? We
don't often think about it, but Samsung supplies these critical
components to Apple at a reasonable price and it supplies them
at a volume few companies could match. Remember, Apple shipped
20 million iPhones last quarter which is a lot of processors and
flash modules in a relatively short amount of time.
