Is there a way to change sound profiles based on GPS position? I thought heard about an app that could change sound profiles based on GPS position, but I forgot which one it was. Is there any way to do this?
The free app android llama can do this. 

Best of all it is not required to use the energy-expensive gps-receiver but can do the same also with "wlan-ids-in-reach" and "cell-phone-masts-in-reach" as alternative.
