The free app "PhoneLock" shows on your phone under the fake name "–NotePad", accessible only with your password. Upon receipt of your secret SMS codes, PhoneLock sends its GPS location to a predetermined email address and/or SMS number, and/or remotely wipes the SD card and the phone's internal memory.
I can't find PhoneLock in the Market anymore. But if you're interested I can maybe send you the .apk file.
