The first thing I really wanted to figure out how to do on the Blackberry was how to get rid of that horrid signature that's on there by default.

Took me a few to figure it out, however, it's actually quite simple to change the default signature on Blacberry devices to whatever you'd like. When you go to the Email Settings under you application screen, you are taken to a page online where you can edit your account settings, however, you aren't allowed to edit the signature here.

Blackberry provides a standard web portal for managing email accounts directly from the web. You must visit this page online using your PC in order to access the appropriate features.

https://bis.na.blackberry.com/html?brand=sprint is the URL that I'm using to access the page for Sprint, I also know that ?brand=vzw works as well from this post.

From here, you can log in using the same username/password combination you would use from your Blackberry handheld.

Once you are logged in, you may select the email account you would like to edit the signature for, and then you will be at a page similar to the one you will find on the handheld, and be able to edit the signature however you wish.

As you can see, I've edited my sigature to remove the horrible "Sent from my Blackberry powered by Sprintspeed" signature, and replaced it with a more coroporate one with the information I like to provide to the people I email.

I figure it best not to let the whole world know that I've got my email at the tip of my fingers at all times now... sheesh, when would I ever have a moment to myself??!!
