Today, Skyfire announced the release of Skyfire 4.0 for Android

, a new flavor of the popular mobile browser, which comes with a nice range of new features, including personalization options for the SkyBar toolbar, and more.

The company added a total number of eight new features to the mobile browser, one of which would be premium in-app purchase for enabling its Video feature, based on Skyfire’s cloud-based servers, and other features more.

Another important fact that the company announced regarding the Skyfire browser was the fact that all existing users will be “grandfathered,” which means that they would enjoy free access on their devices for the lifetime.

The mobile browser was launched in the Android Market in April last year, and already has a number of over 3 million users.

One of the main enhancements included in the new release would be the fact that Skyfire’s SkyBar toolbar is now scrollable and customizable, now with full Twitter, Groupon and Google Reader integration, and more.

The browser's video optimization would be available for $2.99, unlockable via an in-app purchase. However, it would be offered for free to all Verizon customers downloading Skyfire 4.0 for Android. The browser can be found via the V Cast Apps section in the Android Market.

The complete list of new features that Skyfire 4.0 for Android includes is available below.
