Determining+your+BlackBerry+Device+Software+version

 **BlackBerry Device Software Version 4.0 to 5.0**  At this point, you will be able to identify which version of BlackBerry Device Software you are currently using, so now you might be wondering how you can update it in case you need to meet the minimum requirements for an app (like Facebook® for BlackBerry smartphones version 2.0, which requires BlackBerry Device Software version 5.0 or later). You can easily find out if a new version of BlackBerry Device Software or an incremental update is available for you by visiting the Update Your BlackBerry Software webpage. On this website, you’ll be able to review the various methods used to see if updates for your particular BlackBerry smartphone are available. Don’t forget to stop by the BlackBerry Support Community Forums and say hello to our @BlackBerryHelp Twitter® account, as these are two great resources for getting additional assistance in case you have a question about the update process.
