I am using Cingular Sony Ericsson W300i and now I want to unlock the handset. As I was told that it can be done with a code but how to find that? I have decided to skip the network provider because of some problems. And it can be done only after I got the handset unlocked. If anyone has any idea about the cell phone unlock codes, please let it come to my mind. It would be helping me to get rid of irritating network service. Thanks in advance.
