Flixster, a social networking site for movie fans, is doing pretty well for itself in the mobile space. Name any smartphone platform, and there’s a good chance that the Flixster app has spent some time on it’s top download charts. iPhone? Yep. BlackBerry? Yep. Android and Palm webOS? Double yeps.

Earlier today, the company shared with us the news that they’d crossed over a fairly monumental landmark, along with the details surrounding updates for their apps on both Android and BlackBerry OS.

The stats they shared:

• Earlier this week, Flixster crossed over 8 million users across their mobile app lineup.
• Their users are remarkably sticky; of that 8 million, over 75% have used the application in the past 90 days.
• In the mobile apps alone, users are currently rating one movie every 5 seconds, whilst watching approximately 140 trailers per minute, 24 hours a day.

Flixster is also releasing a new 2.0 release of their Android application today, available immediately in the Marketplace. Version 2.0 adds support for Facebook Connect, the Flixster news feed, and mobile access to your “Want-to-see” list.

Last but not least, Flixster also disclosed to us that they’ve just submitted version 1.0 of their BlackBerry application to the BlackBerry App World. A beta version has been available for some time now, but the new version is the first to run entirely in native code, and the first to support access to Flixster’s entire movie database, reviews (both user and critic), along with online ticket. V1.0 will be available in the BlAppWorld pending RIM’s approval.
