What does Unlimited Wi-Fi mean on EE?

I'm getting an Iphone 4 and the deal is
100 minutes, unlimited texts and 750mb of data, but at the side it says *also included; Unlimited Wi-Fi
what does this mean?
My Phone will always be connected to my Wi-Fi at home?

They're saying you can connect your phone to a Wi-Fi network for free. This is a basic aspect of your phone's connectivity and in my opinion they shouldn't be advertising that as a feature they are offering when you pay your Wi-Fi provider separately for this service.
