Bang & Olufsen has thrown itself into the iPhone app realm by launching BeoLink (free, App Store) as a companion to its home theater gear. The app lets an iPad, iPhone or iPod talk to the Danish company's Master Link Gateway over Wi-Fi and can give control over not just the TV, DVDs or stereos but the house itself: it can unlock the door or turn on outdoor lights from the same software. Previously, even the company's Beo5 remote could only work inside.
