For those interested there are of course stipulations and requirements to using the Windows Live mobile application; unfortunately it still is not available for all Blackberry users.
Windows Live for mobile is only available to users of the following handsets: All in-market BlackBerry 7100 Series, BlackBerry 7200 Series, and BlackBerry 7520 Smartphone, BlackBerry 8700 Series, and BlackBerry 8800 Series and the BlackBerry Pearl Smartphone and BlackBerry Curve Smartphone.
Data service plans are also required to use the application; so users will need to check their Service Provider's pricings and rates. Most Blackberry users however already have a required data plan as it generally needs to be set up when the phone is first received.
The application can be obtained on the phone, and from a local PC, on either the official Windows Live for mobile or Blackberry websites.
