I bought an iPhone from ebay and the description included an unlock card (gevey-3) but did not say anything about it being jailbroken. I'm wondering if I can easily unjailbreak it. I know that it being jailbroken will void the warranty but the unlock card does not. So in case anything happens to it I want it to have warranty.
Can I just simply restore it in itunes or will it brick it?
