In a recent report, Skyhook found more than 6,000 location-aware apps for the iPhone, 900 for Android, and 300 for Blackberry. However, only 43 of apps worked cross-platform.
Not surprisingly, the most popular category for location-aware apps was travel, followed by social networking services and sports and fitness apps.
The iPhone had the lowest percentage of free apps (approximately 25 percent), while Android had the highest percentage (more than 80 percent).
