RIM has released a video preview of the company's forth coming BlackBerry 6 OS. The preview showcases a touch based interface, new social features likely powered by technology RIM acquired from Viigo and, of course, a new WebKit based browser. The video, and more information, is after the jump.

Beginning Tuesday night, BlackBerry maker RIM began rolling out its official "Twitter for BlackBerry" mobile application to users by way of the BlackBerry App World site, where it can be found under the "social networking" category.

The app, which has been in beta since April, supports all the features one would expect from a mobile Twitter application, including access to timelines, replies, messages, trends and profiles. But it also includes several BlackBerry-specific options, including push notifications, hotkeys and integration with core BlackBerry apps.

Numbers released from comScore today show that U.S. Internet users watched nearly 34 billion videos online in the month of May, up from just over 30 billion in April. Hulu served up nearly 1.2 billion videos last month, nearly 3.5% of the overall market, while Google remained supreme, accounting for 43% of the market - a whopping 14.6 billion videos - with its powerhouse property, YouTube. Still, Hulu, a place where many watch full episodes of network television, is slowly inching from the pack, and Fox Interactive Media, sitting near the bottom of comScore's rankings, wants a piece of the action. They're target? Mobile.

RIM filed patents for technology that prioritizes different components of a Web page when loading and displaying it according to GoRumors. Specifically, it should make BlackBerry Browser load and display a page's main content before processing CSS and Javascript files. The patents further RIM's efforts to improve its mobile browsing experience as enterprises and consumers increase their reliance on Web apps.

Blackberry smartphone maker Research in Motion (RIM) has just launched a public beta testing site called the Blackberry Beta Zone. Here users can sign up to test pre-lease versions of official RIM products and services and provide feedback to the developers. At launch time, the available downloads include OS 5.0 for the BlackBerry Curve 8520 and 8530, an updated version of BlackBerry Messenger (5.0.1) and, for select corporate testers, Blackberry Enterprise Server 5.0.2.

But what looks most intriguing, though, is the banner image gracing the new site's homepage. It clearly shows a phone running the upcoming official Twitter application for Blackberry.

Verizon Wireless prepares to take on the big names in mobile application stores, including Apple and Google, with the launch of its own carrier-specific "Vcast App Store" next week. Here, customers will be able to purchase mobile apps and pay for them on their monthly wireless bill. The store's launch was announced at the recent CTIA conference, where Verizon disclosed the launch date (March 29) and revealed other details about the store's planned operation. Most notably, the new VCast store has a revenue model that mimics that of Apple's iTunes. Application developers partnering with Verizon keep 70% of the revenue generated from app sales, while Verizon keeps the remaining 30% for itself.

The Blackberry outage that RIM does not want to talk about continues to affect people on both sides of the Atlantic with outages reported in the United States, Canada and the United Kingdom. Some people have been without service for more than 24 hours.

The outage is a peculiar one, Data Outage News reports:

"Again, this is affecting devices on all North American carriers, BIS and BES, and it appears to be only devices on WiFi, wherein data works "sometimes" when connected via WiFi; no data when WiFi is disconnected."

At the recent Mobile World Congress 2010, Dutch app store analytics firm Distimo presented their findings on the six largest mobile application stores in existence today: the iTunes App Store, BlackBerry App World, Google Android Market, Nokia Ovi Store, Palm App Catalog and Windows Marketplace for Mobile. In their presentation, they analyzed everything including store size, store growth, the most popular applications and where you can find the best deal. They recently shared some of the highlights from that presentation by way of a slideshow embedded on their blog.

IBM and Research in Motion announced a partnership today to sell Blackberry devices fully loaded with IBM's collaboration software. This is the first time IBM has sold Blackberry devices into its business channel.

Lotus Quickr, a document sharing application, and Lotus Connections, a social-software technology that helps users find people with a particular expertise, will now be available on the smartphone.

Blackberry users had a bit of a surprise this morning. Email was down. It came back up around 11 a.m. PST but in comparison to prior outages, this was a big one.
