SEOUL, Sept 1 (Reuters) - South Korean shares were little changed on Friday, as investors turned cautious ahead of inflation and exports data, with exporters such as Samsung Electronics also flat, following recent strong gains and ahead of U.S. employment data. Kia Motors Corp. shares rose 1.96 percent to 15,600 won after the country's second-biggest auto maker said it had reached a tentative wage deal with its union.
