I've had my Blackberry about a week now, and after going through the post/threads, the Blackberry website and manual, I still can't my change the signature on my phone or Desktop Manager.
I'm on the Sprint Network, Curve 8330.
I can pull up the signature on the phone under email settings, , edit, then go to the bottom to the signature, but it won't let me change or delete it.
Click on this link here BlackBerry Internet Service and login, then select the email address you want the signature changed on, that's it. If you don't have the password info, call your carrier and tell them what you're doing, they will reset a new password for you in a few minutes...
Thanks, I went to that page, setup my email, etc.s when I first got the phone and forgot about it. I changed the signature on my email, after I tried to create a new account and it told me I already had one. LOL
