I live in shanghai china.

My question is

1) my employees are using iphone 4 (bought in Asia) and i like to know if mobile spy supports China Telecom and China Unicom?

2) how much data ( for sending information to mobile spy ) would be incurred per month on average ? i understand GPRS would be needed to upload all the information to mobile spy website . Would it be very large ? 50mb ? 100mb ? Because data charges are very expensive in China and i do not want to incur the heavy cost on handphone bills .

Thanks . appreciate if you could give me the answers i need .
