Hi and Welcome to the Forums!
For BIS-based emails, go into the BIS interface (Homescreen > Setup > Email Settings -- or via your carriers web interface from a PC/browser). The signature field is within there.
For BES-based emails, go here:
Homescreen > Messages > > Options > Email Settings
Select your BES account (often "Desktop") and change "Use Auto Signature" to "Yes". Then type out the auto-sig you want to use.

Are you BES or BIS?
