Greetings, I have been trying to google an answer to this but I seem to find equal numbers of postings saying its possible and its not possible so I thought I would try here. Is it possible for me to just find out my unlock code and then use it to unlock my phone? or do i have to send it in to somewhere or buy a cable and software to do it? Again the phone is a Sony Ericsson w300i currently locked to AT&T in the USA.
