I just feel like telling the whole world that I have successfully unlocked my Sony Ericsson W705. I am now able to use worldwide SIM cards that support GSM 850, 900, 1800, and 1900. Speaking of which, I am currently using an AT&T SIM card provided by my epic cousin who lent it to me for the week while my family and I are visiting in Los Angeles. Anyways, I am having fun in Disneyland, so I will talk to you later!
A side note: The program that was used to unlock my Sony Ericsson was Omnius. It works for other Sony Ericsson phones as well.
