Att likes to keep their phones very locked on their stuff so when your uploading a OS ir recognizes that is an att phone so it will usually load up the att theme icons ect. I managed to remove the push to talk icon it was annoying
So I changed the vedor I'd # on the att to a tmobile vendor Id# and I unlocked the verdor themes for for tmobile it removed all of atts icons and uploads the tmobile icons once I connected the bb to desktop manager.
