Amazon’s Kindle 3G e-reader is becoming popular on China’s grey market for an unexpected reason. It can automatically circumvent the so-called ‘Great Firewall’ of the state’s web censorship. Social networking sites, which Beijing blocks, can be accessed without interference by the Kindle. Amazon say they are not allowed to export the Kindle to mainland China, but many are believed to have entered the country illegally. The 3G Kindle uses global system mobile (GSM) communication technology, which is able to provide WiFi coverage in China.
