    Has anyone else seen this:
    http://www.engadget.com/entry/1234000637030517/

    It says to unlock the GSM version of the Treo 650 by entering the sequence *#*#1234# and then pressing the center D-pad button.

    Can anyone confirm this?

    This procedure works but not remove any firmware-based Cingular-specific entries that will re-appear after a hard reset...things like entries for Cingular Accesories and Cingular Customer service that appear in the contacts list, the cingular splash screen at startup - which can be removed temporarily. Remove these and they re-appear after a hard reset. No biggy though. Works.

    Cool, It also works on the Treo 600.

    As been posted in other threads, THIS IS NOT A SUBSIDIARY UNLOCK. This is only the default unlock code if you locked phone. The subsidiary lock on any GSM phone is based on the IMEI number. This means you need a different code for every single phone, there is no way a single code will work for multiple phones.
    Main Phone: Treo 270/600/650/700w/700p/750v/Motorola Q/iPhone
    Tried but sold: Motorola Q/Nokia E61/700wx/HTC TyTN/Treo 680
