Apple has released iOS 7.1 for iPhone and iPad, and Leo says users should run, not walk, to install it. It solves a lot of problems that have creeped up. It does seem to have battery problems, however. Leo advises resetting the iPhone after you update it, that should clear out the "cruft" and get it back to it's usual battery life. Leo advises going to Settings > General > Reset > Reset All Settings. Don't choose the "Erase All Content and Settings," as that will erase all data as well.
