If you are an avid Facebook user, you may be interested in syncing your BlackBerry with your Facebook profile, giving you access to your account from anywhere your phone can go!

The Facebook application is available in multiple languages and allows you to monitor your messages, your wall posts, your status updates, and of course easily add photos.

MySpace is by far one of the most popular websites on the internet, although not always for the most positive reasons.   Regardless, many BlackBerry users have a MySpace account and want to be able to access their account from their smartphones.

There is now an official MySpace BlackBerry application available on RIM’s website.  With this application you can:

• Send and receive MySpace mail
• Update your Status and Mood
• View and send Bulletins
• Add comments
• Post your photos

Edit:  It appears MySpace 1.5 is now available to BlackBerry users.   Here are the new features:

• Friend Updates: Users can now view their MySpace Friend Updates from within the application, and click on a thumbnail of a photo in the Friend Updates to be taken to a full screen version
• Enhanced updates and messaging: Instantaneous mobile notifications and messaging (no lag time between receiving a message online and on mobile). Users can also save a composed message/bulletin as a draft, delete and open a saved draft message to edit/send the message, and view or hide sent items
• Enhanced band profiles: Bands can add tour dates and more profile bits to their profiles, like Upcoming Shows (displays more details on the show such as venue, date, address and cost)
• Support for French, German, Italian and Spanish languages
