Can you use a turned off iPhone 4 with Wi-Fi?

Hi, my friend is giving me a free iPhone 4 because he got a new phone. The only thing is, I'm not going to turn it back on or get a data plan or anything. Can I just use Wi-Fi for it when I'm at home? Basically i just want to use it as an ipod touch.

Yes, you definitely can use it with wi-fi without any plan.

You should be able to.

Yes you can I'm using my iPhone right know and there's no plan on it all you do is plug it into iTunes and restore it

Of course, you can.

Yes! Have fun!
