If you have a smartphone running on Android 2.2 (Froyo) or Android 2.3 (Gingerbread), I recommend you to upgrade your Android Market to the latest version 3.1.3. This is the new release, more recent than the previous Android Market 3.0.26 / 3.0.27.
You can download the APK file of this new Android Market 3.1.3 from any of the links listed here:
This is how the new Android Market 3.1.3 looks like.
Its starting page is the Featured list. It has separate navigation listing for Top Paid, Top Free, Top Grossing, Top New Paid, Top New Free and Trending. You can filter the listing by Categories and the result will be listed accordingly.
The Android Market 3.1.3 introduced Google's +1 feature, so you can +1 the apps you like.
Press the Menu button of your Android phone, and select My Apps to view the listing of the apps installed in your phone.
Another remarkable new feature in Android Market 3.1.3 is the PIN setting security for making purchases. You might be aware that previous versions of Android Market will let you make purchase of new apps with your Google Checkout account just by tapping on the Purchase button. If you let other people use or play with your phone, you have to be alerted that they can open the Market app and start purchasing paid apps using your account. Now, if you have set a PIN and locked down the purchase function with your PIN, that danger won't simply happen anymore.
Note: If you have an Android tablet running on Android 3.0 (Honeycomb), this Android Market 3.1.3 upgrade might not be applicable to your device.
