BBTracker—Record Where You've Been via BlackBerry

The bbTracker application is an extremely simple, easy-to-use piece of open source software that could prove particularly valuable to road warriors, athletes and outdoorsmen. GPS functionality is a must, however, so users need a device with internal GPS or an external "puck."

bbTracker

The free BlackBerry download tracks users' coordinates and/or altitude; records recently travelled paths, which can be displayed via line graph; tracks and charts elevation and speed over a given time period; and then exports it all to a mapping service like Google Earth so you can follow a path you travelled while carrying your BlackBerry. The software is not a full-fledged GPS application, though, and as such it does not provide on-screen maps or directions.

bbTracker can be downloaded OTA, and its source code is available here.

BlackBerryTools

BlackBerryTools is not a single free application—rather, it's a package of five open source downloads that give users more control over BlackBerry functions like backlight, message reply options and spell checking. The utility also offers various weather and device status information, like battery life and messages received.

BlackBerry Tools BBToday Screen

BBLight lets you modify your device's backlight setting so your display can remain lit for as long as you desire. BBToday displays the date, current time, messages, appointments and tasks. Weather information and forecasts are available via BBWeather. BBReply helps modify your message reply-to addresses, and BBCorrector helps spell check message.

The five BlackBerry Tools are available for individual OTA download, and their full source code is available here.
