Dear All , I took a Galaxy S from India , Currently in China and trying to get GPRS worked for this phone .. I have tried all possible ways of setting up APN with the help of China mobile call center and service center but still its not working on this phone . I was able to use the GPRS in India without any problem. I am setting the APN with cmwap and proxy setting 10.0.0.172 / potrt 80. Is there any other setting required apart form the APN setting ? Is there any need of phone S/w or firmware upgrade for this ... Anyone tried please reply ... I am really struggling with it for last few days ..
