Just browse thru the business sections of iTunes and you'll find all kinds of goodies you can't live without! You can invoice, email, scan, fax, setup a free separate line for business, I just downloaded an app from Intuit that allows you to take credit card payments. They even send you a free credit card scanner that plugs into it. If you have to use walmarts service channel you can access it from there also. Pictures and video look amazing on it but they're only the tip of the iceberg. I have the same apps on my iPhone 4 also, you can literally run your business from your phone. Lemme know if you get one and need any help with the setup.
