Panic Button

Panic Button for the Android phone has been released in the Android Market.
Panic Button allows you to preset a distress message. It also allows you to select contacts who should receive the distress message.
It has a countdown before it starts sending the messages to prevent accidental use. It will then send your message + your current address and the GPS coordinates (and accuracy) to the selected contacts.
Once activated it will send new text messages (sms) to the contacts every five minutes (only if the location or accuracy has changed).

Example message:
I need help! My location is Amphitheatre Parkway, Mountain View, CA 94043, USA. GPS Lat X.XXXXXX, Lon Y.YYYYYY. Accuracy 50m.
