I just updated to IOS 7.1 which I believe is the latest version. I am using an iPhone 5 32 gig. When I updated my phone, it seemed like the enitial update didn't fully install, so it prompted me to update again. So I proceeded to update the darn thing and it installed correctly. When I got to my password screen to to log in, it froze up on me and it took a while for it to register the letters that I'd pressed. I have an external keyboard which I used and it also froze. I am concerned because I don't know of a way to restore the update. Help would be greatly appreciated!!
