So do you think jailbreak have somthing to do with the wifi problems that makes the wifi greyed out? I'm asking because my previous Iphone 4S got the wifi greyed out, and it was jailbroken. So I got it replaced, jailbroke my new device and two weeks later the wifi was greyed out again. I'm now looking to buy an Iphone 5 and am therefor curious to know if jailbreak has something to do with the wifi problems I've been having? In the store they said it hapens all the time and they weren't shocked to hear that it happened for me twice. So I don't know if the 4S just tend to get these kind of wifi problems or if it's because of the jailbreak.
