If i don't have a data plan, but have an iphone, what can i do on it?

My dad got an iphone 4s, and wants to give me his old 3g.hes going to give it to me, but i can't afford the data plan. So if i have an iphone, and no data plan, would i be able to go on the app store, buy music, etc?

You could use it to surf on wi-fi networks.
Download music and use as an MP3 Player

Almost anything except make calls… You may even be able to do that with a wi-fi connection and skype

You can do absolutely nothing, other than make calls and send texts. You can use it with Wi-Fi, but your carrier will not let you add the phone on the account without a data plan.

Obviously, there's this thing called Wi-Fi: p.Yes you can do everything with Wi-Fi and it doesn't take much battery life as a data plan. If you want to make calls from your phone get a cheap package without a data plan.
