12/13/2013 17:50
Apple has recently seeded beta 2 of iOS 7.1 to developers. This seed includes some more minor fixes from the first beta seed, which was released about a month ago. There were many new things added in iOS 7.1. Some of them are bug fixes, added option for a dark keyboard under accessibility, new upload options for burst mode on the iPhone 5s, and more. We aren't sure when this version will come to the public.
Also, as noted by 9to5Mac, under Restrictions there is an option to allow or not allow Car Display. This will allow you to use your iPhone in supported cars. However, this feature is not live yet. We are expecting this to come out in early 2014.
