Apple announced that it was releasing updated mobile software for the iPhone and iPad which makes it easier for users to get on high-speed networks. The iOS 6.1 version, which updates the one released last year, includes Apple's own maps program which drew scorn from users because of numerous glitches, and which Apple has pledged to fix. The new software allows 36 iPhone carriers and 23 iPad carriers around the world to provide access to the faster LTE (long-term evolution) networks offered in many locations.
