I have a locked iphone but can't get it to work at all even with wi-fi?

It won't connect to itunes and I can't use it to play games, camera, apps etc. What can I do?

Don't you have 3G?
if you don't i think it is broken (it could be the Wi-Fi your using)
i would suggest to go and have it checked

Is there a refresh button on the side of the phone? Press it if there's or try connecting to a different Wi-Fi.

I want a friken iphone!

Any iphone you have you need to first activate it buy using the sim card of the provider. Once you activate it then you can start using the Iphone. The sim card has to be of the same provider.differnt number but sim has to be of same provider.
THERE's NO OTHER Way TO ACTIVATE IT.

Once you activated the phone You can remove the sim card & you can go ahead & use it for the Wi-Fi only mode.

Hold down the top power button and the menu buttons at the same time and wait 5-10 seconds then release, your phone is pry frozen or attempting to give you the green screen of death. This should work I have had to do the same thing only with a iPod touch 4. If that doesn't work plug it into your computer and restore it to factory settings, you may have to do both of these things a couple times in order for it to work.
