Ask iPhone-toting Sonos speaker owners about their biggest gripe and they'll probably point to the lack of at-a-glance controls. You have to launch the app every time, which is a pain when you just want to pause a song from across the room. Life is about to get much easier, though: Sonos has updated its iOS controller app to introduce lock screen controls. They behave almost exactly like what you'd see for on-device music playback. The only big difference is that it'll identify both the source of the tunes and where they're playing. You can't switch rooms or audio sources, alas, but it's still far more convenient than unlocking your phone.
