I just purchased an Equinox TM717 from T-mobile (U.S.A.). It is not listed in the list of phones on this site. Is it already an orphan? How can I update its software?
Many times T Mobile and ATT give free phones that are older. You may want to check in www.cnet.com reviews for the model and/or on the Sony site and if you cant find the phone return it for a newer model.
