I have had a 7100i for a few weeks and for a while there I could send emails no problem but now for some reason I can receive email but can not send it. does any know how to fix the problem? Also, does anyone know how to edit your BB so it doesn't add the little black berry thing at the end of your emails and edit your MMSs so that it doesn't add your phone number? Most phones know where their MMSs are coming from so it is unecessary to have you r Phone # automatically added to the body of the message?

You can edit or delete your signature at your BIS site:

Try resending your service books for the email issue:

Good luck.

I trid loggin in to the web site you suggested enter the info requested and it is giving me a variety of errors, even though i am certain I am giving the correct #'s etc. Very dissapointed with nextel so far

That's the link to do what you need. You may need to call nextel and get your pw reset or something if they can.
