Hi guys, my iphone is showing some problems and I'd like to take it into the genius bar. (Camera intermittently shows pink colors or doesn't work at all). Only thing is, I don't have my SHSH backed up (I had to exchange the iphone not too long ago) and I really don't want to be stuck at 3.1.3. Is there away to hide the jailbreak so that it's not detectable to the geniuses?
