Llama is a Location Aware Mobile Application.
It uses phone masts to determine your location, so that you can change your ringer, vibrate and ringtones depending on where you are as well as the time of day. Llama provides you with sound profiles so you can quickly switch between quiet, loud, silent and normal sound settings.
It can also run applications, turn your wireless, Bluetooth and APN mobile data (GSM only) on and off.
NOTE: Since GPS is not used, the location tracking is limited to the number of phone masts in your area. This will work best if you live in a populated area.
