Hi guys, I have a iPhone 4 and will be getting a iPhone 5S as soon as my contract ends in December. In the meantime I would like to use iOS 7 on my iPhone 4. I have jailbreak on it and it's on 6.1.1 or 6.1.2. I don't care about the jailbreak features and want to use the Apple iOS 7 but I don't know the correct way in doing this and not screw up my iPhone. I just want to keep all my contacts, texts, email, pictures, music. If someone could guide me with an easy way that would be great and appreciated. Thank you.
