I've got that stupid ATT signature in every e-mail I send! Also, when replying it's including the original message. It says this can be changed by logging into the blackberry ATT website from a PC.
How? I don't even remember selecting a username!
Also, when I put in my PIN under forgot password, it sends me a message saying no account set up. It works from my BB, but says I have to change the sig from a PC. Have been waiting on hold with ATT for 36 minutes.
