The Signal: RIM Takes Another Hit

Another Hit for RIM: Twitter app Seesmic just announced that they will no longer support Blackberry devices starting June 30 because they would like to “focus development efforts on our most popular mobile platforms: Android, iOS and Windows Phone 7.” Ouch, that’s got to hurt, RIM.

New Foursquare Features: Foursquare has made checking in even easier by putting a check-in button right in the middle bottom of the app screen on its new iPhone app. Also there is a new “Specials” button in the Explore tab that lets you browse nearby specials. TechCrunch

Zune Back to Life: A recent Zune Insider podcast confirmed that Microsoft is porting over native Zune apps over to Windows Phone 7. Whether or not they will port over third-party Zune apps will depend on the developers. SlashGear
