Is there a simple program out there where I can just download my address book to my computer, then add contacts and put additional data in such as e-mail address, company names etc and then upload the new information to my 8830?
Thanks for your help.

Outlook is almost certainly your best bet.

^^ exactly as stated. Outlook Express is free but doesn't have a calendar I believe. But it will sync your contacts well.

I have never liked Outlook but it is the standard for Corporate America. I have always wished that RIM would come out with some simple desktop PIM like Palm had for use with the Blackberry.

What the heck happened to Palm anyway?
