I have never used the wifi on my 3g and was wondering how I connect to it? I do have a wireless router in my house I am just not sure what code or password I need to enter into my iPhone to get it to work. And once I put it in do I need to keep entering it in whenever I am home and want to use wifi? Thanks

Teek is right. You'll only need to enter the password once. From the Settings icon go to Wi-Fi. From here it will bring up all available Wi-Fi networks in range. Choose your router , you will then be prompted to enter the password for the router. You are then good to go
When I leave home I turn wifi off because otherwise when I travel throughout my city, it tries to connect to city's public wifi (which doesn't require a password) and the signal is weak.
I'd rather just use the 3G connection when I'm not at home.
