Hello, i'm new to these forums, therefore any help to my queries would be very gratefully recieved. I have an iPhone 5, running 6.1.4, however i would like to run iOS 7 on it. Without a registered UDID, would i be able to: 1) Install beta 4 without bricking my phone? 2) Be able to restore my phone from a back-up so i have all my contacts and photos on it as i do now? And 3) Recieve OTA updates? Thanks in advance.
