Wi-fi and email, AIM

I didn't sign up for a data/internet plan because my curve already has wi-fi on it. Is there anyway that I can still have my email forwarded to my cell with just wi-fi? Its very annoying to go to my email website and sign in everytime.

Can I use AIM on wi-fi? I've tried to log in on AIM, but it says I have to go to blackberry.com/aim, but when I try to sign-up or register something on my computer first (on 3 of my computers, forbid me to go through with it. I've tried logging onto AIM.com, but its hopeless.

TIA!:)
