On Monday my phone kept rebooting itself every few minutes at work. When i got home I managed to reset it and get my stuff back from an iCloud backup. It was all working fine until yesterday. Used it fine in the morning and at lunch called my partner. Strangely I couldn't hear it ringing. To my dismay I looked at the phone and there was the dreaded Apple logo. "Not Again" I thought. So I pressed the power and down volume hoping it would bring it back to life and nothing. Have tried leaving it on charge for many hours too. It's a brick. When it happened the phone was nearly fully charged. I bought the phone on release day straight from Apple so luckily still under warranty. I have a genius appointment tomorrow. Does anyone know if I will get a refurbished one or a new one? I really wish it hadn't happened and have learned my lesson because I didn't make regular iCloud backups so have lost most of my recent texts message etc now. Anyone else had this happen completely out the blue? it's never been near water or knocked/dropped at all and is in pristine condition.
