Apple has taken second place in the large and growing smartphone market in India by using a clever workaround on its pricing. While offering its iPhones at roughly the same prices worldwide, in the India market the company is now employing a "trade-in" promotion with its reseller partners that has tripled sales in the space of a week. The lowest-priced model -- the iPhone 4 -- is now outselling the iPhone 5 as buyers trade in old smartphones for a discount of at least 7,000 Rupee ($129) off the $488 price of the iPhone 4.
