  • Will updating Iphone 3GS to ioS 6.0 ruin screw up my jailbreak? I don't know how to ask this… Sorry if my wording makes no sense. I have an Iphone 3GS, and I want to update it iOs 6.0, but won't that take the jailbreak or whatever off? And I will have to jailbreak it again?

I have never even touched the screws, but I'm assuming when I tried to sell my iphone with uSell.com that the technicians there did and I tried the super glue trick to unscrew the screw but all I got was super glue stuck in the screw… How do I get that out?!
