The Pebble smartwatch nicely alerts you to most of your smartphone's activities, but it's pretty limited in controlling it -- there are just a few functions, like music track skipping. A new 2.2 firmware update finally gives a much-requested feature, however: changing the volume of your phone's music player. That, along with a new iOS-only track progress bar, will help you avoid reaching for your handset when you're grooving while running or biking. You can finally rearrange apps directly on the watch too, and will get longer alarm sounds and some bug fixes. You can grab it by going to "support" in your smartphone app, then choosing "check for updates." Apple users will first need to hit the App Store for an iOS update.
