China Mobile and the iPhone's GPS

(China)

I bought an iPhone last week in HK, all operations in China is very good, but does it support China Mobile's network in the iPhone GPS ? Does this function work in China ? My iPhone just say "can not determine the location," when I try, anyone know this ?

Answer:
If you have a data plan of China Mobile, you need to go to settings: Settings-General-Network-Cellular Data Network, and input CMNET of APN. Once you get into this, it should are beginning to work.
