My iPhone 5 has been playing up these past few months, kind of lived with it but its getting frustrating and now concious that the warranty is up next month. I've tried a restore and a restore without restoring the back up and I still get the same issue, sluggish menu/switching between apps/menu, freezing up and even blank screen .. all are ocassional issues, but got the blank screen last night and only way to get it back on was to do a hard reboot. I have an appointment at the Genuis bar tomorrow morning. Are they likely to swap it for a new/refurbished handset for me? I had an issue with my 4S previously and I was suprised at how quick they were just to swap it, but I hear they are now repairing some issues in store so I'm wondering if there has been a clamp down and they are now more reluctant to swap them?
