Lately I've been having issues with my 4S and freezing up. When I tried to read up on in this, it was suggested that I reset my phone (top and home buttons) and that might do the trick. Now, if that didn't do the trick, then I would have to restore to new condition. It said not to restore from a backup as the backup might have the bug causing the phone to freeze. If you do restore to new condition, how do you go about saving all your contacts? Thanks!
