Every month we bring you a roundup of free applications for the Blackberry smartphone. The four applications that have been released in March are awesome programs that are a must-have for every BlackBerry use and that you should definitely give them a try. Since all of them are free, I don’t see any reason why you shouldn’t.

Formula 1 Live Tracker

The Formula 1 season has started and not just racing cars are using the latest technology. Formula1.com has released a free live timing application for Blackberry smartphones. With this app you are able to track the progress of every driver live as it happens on the track. You can also check status indicators informing you about flag status and safety car phases as well as text commentary about the current race. You can also find information about circuits, weather information, air and track temperature. To download the app visit mobile.formula1.com directly on your Blackberry smartphone web browser.

Free IM+ Lite

E-mail on your Blackberry keeps you connected. To stay in touch with other fellow Blackberry users we can use Blackberry Messenger. If you want to chat with people on other instant messaging platforms until recently you were only able to use IM+ which is a quite expensive instant messaging application for Blackberry smartphones. Since March there is also a free, ad-supported version of IM+ available and you will be able to access MSN, Yahoo!, Gtalk, AIM, Jabber, ICQ, Facebook, Myspace, Skype and Twitter.
