I am sure this has been answered but could not find the post. Is there a way to remove the message sent from my blackberry when you send a text, etc.?
For email go into settings folder then email setup and click on email address. This will bring up your information. Here you can delete the message or create another one.
As far as texting the only thing that can be done I believe is removing your call back number. To do this go to options then SMS Text. Here you will find the number. Clear it off then save.
Hope this helps.
