Hi,
If you're looking for a simple compass, you might like Compass Lite for the Storm 9530 and Tour 9630. It uses the built-in GPS in the device to show your line of travel, speed, latitude and longitude and where North is in relation to your heading.
Like most of these GPS-based apps, to establish a line of travel, you must be moving.
Available through our website, MobiHand and through the CrackBerry Store here
It's $.99 USD
