I just got my Iphone 5. I had an iphone 4s running ios6. I backed up my 4s and restored that to my iPhone 5. All is well except that when i try to move my icons around, i press the home button to finish and almost every time the screen goes black, i get an apple logo and then back to the springboard. and none of the icon moves i made stayed. they are back in their original location. this is very frustrating. Any idea how to resolve this one?
