Email Marketing

I NEED TO PUT A DIFERENT PORT TO RECEIVE AND SENd EMAILS.

I have been to used bookstores and see people with candy bar cell phones (or at least it looks like a cell phone) and they are pushing the ISBN into the phone. I think it has a database that gives them the market value of the book. Does anyone know how this is done? What program can you download to your cell phone? Or is this a PDA that looks like a cell phone? I am technically challenged, but I would really like to have one of these also. Thanks for any and all input.

I am going to be moving from this company, and they are letting me keep the Blackberry. How do I ‘turn off’ the email capability for the Microsoft Outllook portion of my phone?

I want it to function as a normal phone, just without the email. I don’t need the email anymore but I’ve become accustomed to the keypad and like some of the features. Thanks!
