Hey guys, My iPhone 4 (which I purchased a couple weeks after release date last summer) is plagued with the camera perma-shutter (where the camera's virtual shutter never or seldom opens, rendering the camera functionality useless). I have AppleCare and plan to get a replacement phone...I have SHSH blobs saved on my currently jailbroken phone running tethered 4.2.1, but if I do get a replacement phone, will I still be able to jailbreak (i.e. untethered 4.2.1 via greenp0ison, or whatnot)? OR, does anyone have any solutions to the shutter issue? I've read a lot about it online and it seems to be a hardware fault and Apple has just been handing out new phones to people who have the issue. Thanks!
