Where in Nanjing can i get mobile with international version

As I know, any smart phone has multilingual settings. Personally, it is ok to buy a branded mobile in China, such as Iphone or Samsung to set the language.

Near the Gulou Square (North Zhongshan Road), there are several malls sell mobile phone exclusively. You can just go there and purchase one. Or go to the local Segbuy Mall to have a try.
