I have figured out everything on this phone. Except for how to change the tones for text messages! Not ringtones, but texts. This phone did not come with a user's manual, but with a disc. When I accessed the disc it brought me to the at&t page that featured the phone, but no user's manual. I did see where you could download a manual, but I can't download on my computer. Is it even possible to change text settings?
