Bought IPhone off Craigslist?

I bought a iPhone off craigslist. It was rested, I use strait talk but it required a iCloud name and password?

Wish we could. You got ripped off. That's why the deal was so good. ICloud is a security feature that blocks activation when it's reported lost/stolen. Only the original owner can remove the phone from her/his account to make the setup work. If you don't know them or they refuse, all you can do is try this.

Success rate is real low on cracking it. Best luck.
