I have a brand new iPhone 5 (manufactured in Oct 2012) which has iOS 6.0 on it. How good is this version? So far, everything seems great. Very fast and fluid on my phone. Battery life seems fine. I am wondering what issues plagued this version (if any)? I have also done some research to see if I can update to iOS 6.1.4. I have the IPSW file, but I don't think that will work, which is a complete shame. I do not want to update to iOS 7 and loose the the classic iOS 6 look (which is really much easier on the eyes) Advice?
