What is the best way to exchange my iPhone 5 in the UK that has a problem with the glass not being fit properly on the right hand side? Can I just take it to my local Apple store (Meadowhall) without booking an appointment to get it replaced? And how long do I have to do that to ensure I will receive a brand new phone in return? Also, I got Ghost Armor applied on the same day as purchase right out of the sealed box in Manchester Arndale shopping centre. This cost just under £30...am I going to be now made to shell out another £30 to get it put on my replacement iPhone?
