bbTracker - bbTracker is a simple application for Java-enabled smartphones to create GPS track logs. It tracks ones movement and provide that data for later analysis. It is not meant as a replacement for full-featured GPS software that does display maps and do path-finding, but rather a simple tool that does one thing and does it well. It works with built-in GPS units, as included in the BlackBerry 8800 and the Nokia 6110. Alternatively it can use a external GPS puck via Bluetooth.
