When I send an email from my blackberry, the receiver receives a message saying...Sent via BlackBerry from Cingular Wireless. Is there anyway to get rid of that message?

How can I view email attachments?

Check in your Message Options --> Email Settings and you can set it in there to use or not to use the auto signature. You can also create your own auto signature in here. Hope this helps!!

You didn't say which BB you use, but this is how it is with my 8700 and BIS.

Question 1. If you are on BIS, log in and select EDIT for the email account you wish to change. Go to "SIGNATURE" and replace with what ever you wish. Then hit "SAVE" and log out. That signature block should show on all email sent from that address.

Question 2. Highlight the attachment with the wheel and then click and go to "OPEN ATTACHMENT"

I have an 8700c.

Dubdub, I don't think I saw "open attachment" when I followed your steps. I thought I read somewhere that if open attachment did not show up, then a program needed to be downloaded. I'll re-check it later.
