Getting a SIM in China

Previously I was worried about getting a mobile connection in China , found out it was very easy , I went to CArrefour , went to the phone department , ask him for a SIM , filled out a form and got the SIM , it was activate for GPRS , paid RMB 160 for total package with 50 min btw also found out that E 70 is not available in China , the Carrefour guy was very interested in the phone :)
