Can i use ebay iPhone with Wi-Fi?

I'm looking at a Verizon iPhone 4s on ebay. Can i use it without a carrier and just for Wi-fi? I do not want to pay for any service and just to use with Wi-Fi.

If you're not using it as a phone, why don't you go for an iPod Touch?

Yes this is exactly what i have been doing for the past year, i buy the phone on ebay and just conncet to my Wi-Fi at home, your not obligated to connect its service

Yes, any iPhone will work with wi-fi, with or without a cellular service contract. You don't need a SIM card at all for wi-fi service.
