Some Android [Apps] Quietly Sending GPS Coordinates to Advertisers.

"Researchers from Duke University, Penn State University, and Intel recently got together and did a little digging through the Android marketplace. They chose 30 of the most popular apps, installed them, and then monitored their every move. Half of the apps evaluated were found to be sending private and identifiable information, including GPS coordinates, phone numbers and IMEI numbers back to advertisers. The researchers used a custom-designed app called TaintDroid to monitor the applications, and were disturbed to find GPS coordinates being sent back to ad providers by 15 of the apps in question."
