Do I have to jailbreak and unlock my iphone 4s if its never been activated?

I bought it not knowing it was Verizon and I want to use it with AT&T. It's running on ios 6.0.1 and it says it's never been activated.

Can't use a verizon 4s on att, not possible unlocked or not.
if you need an att iphone email me

Unfortunately that mistake costed you whatever you paid for that phone. There's absolutely no way to get AT&T service on a Verizon iPhone.

It is not possible sorry.

You won't be able to use a verizon iphone inside the US if it's unlocked… It will only work overseas.
