Another update to the Android Market is pushing out to your smartphone, and we're liking what we're seeing. There are a couple of new features you need to know about. The first is that you can now +1 apps from within the market on your phone. That's a good thing, and you should practice on this one. The other is that you can now set a PIN lock on market purchases. That means you'll have to enter a code any time you want to buy an app -- but it'll also keep someone else for charging things for you, too.
