Need to take my 6 to genius bar for replacement Finally at a place I am happy with tweaks etc and now I have to take my phone in because it has a loose screen in the top left corner. What's the best way to go about it? Should I risk taking in while jail broken because I don't want to go back to stock and be told they won't replace the phone? Any way to back up and restore tweaks/apps from Chris? Cheers!
