Following weeks of scrutiny over its warranty policies in China, Apple CEO Tim Cook says it has improved services in the region. The info came in the form of a note posted in Chinese on Apple’s Chinese site.

According to “CNET” (http://tinyurl.com/c6zzsfm), in the letter, Cook apologized for a lack of communication on the matter, and said that the company is implementing improvements in three areas of its warranty policy and related services:

° A new repair policy for the iPhone 4 and 4S that provides a new phone exchange or new parts replacement for a year after purchase, and extends warranties on those devices repaired within the last year.

° New warranty explanation pages on Apple’s Chinese site.

° More training and policing of Apple Authorized Service Providers who are doing repairs.

The company also pointed to its online feedback form for anything that falls outside those changes, notes “CNET.”
