Google has updated the Market app for Android today which brings some pretty major all-new features like the ability to +1 apps, use custom PIN code for purchasing apps, tapable app permissions and a settings menu for more options.

The two greatest new features for us is a. the ability to +1 apps and b. use a custom PIN code. To add a custom PIN code, open up Market: Menu button > Settings > Set or change PIN.

Rest of the updated features are nice little additions to the ever improving Market app: App permissions can now be tapped to read the details of each required permission and the settings menu now comes with more options.

To do this, simply download the .apk file to your Android smartphone from the link embedded below and install it. You must have Unknown sources enabled from Menu button > Settings > Applications in order to install the .apk file.
