Android Market gets 3.1.3 update, brings +1 button, PIN support
Google has started rolling out a new update for Android Market out of the blue today. This update has some new additions including the +1 Button and PIN lock support. With the added PIN support, the fear of accidental purchases by your kids/family will go away.
There are a few aesthetic changes too, which will probably go unnoticed. Anyways, if you can’t wait for the official delivery on your device, you can grab the download from here.
