e-mail client. Just wondering if there is any kind of e-mail client that I can use on my BB. Something like outlook.

What you see is what you get. You can sync contacts and calendar info with Outlook.

Check out PocketDay and I have heard that there is BB version of PocketInformat in the works. No release date or other info however.

Exactly what are you looking to do?

I just want to send and recieve e-mails someway kinda like outlook.

The BlackBerry itself is the email client. That functionality is built into the BlackBerry operating system
You don't need any additional software.
You only need a BlackBerry Data Plan on your wireless account.
