I don't know about all of you, but for me, this has to be one of the most useful apps on the market.
If you lose your phone, you can just text a code phrase to your phone and it will start to make a noise so that you can find it.
Before it starts to make the noise, it will turn the volume all the way up. So, it even works if you had the phone on silent or vibrate.
If that's not good enough, you can text a different pass code and it will send the GSP location in a return text.
The name of the app mentions a Droid. However, my phone is an Android and it works perfectly.
