I appear to have lost my Streak somewhere in my apartment, and I can't call it since I don't have a SIM card in it. I've remotely installed Plan B just because, but unfortunately the GPS coordinates are not specific enough to find it inside my apartment :P. Is there any app I can install remotely that will start making noise so I can find the device?
Bahh! Just found a way to do this! I'm so excited!
First, install AndroidLost from the online Google Play Store.
Give it a little time to install to your device, then install AndroidLost Jumpstart from the online Google Play Store as well
So you have to install an arbitrary app from the Play Store as well to activate the service, but you can then go to androidlost.com to access functions to control your lost device! Including ringing an alarm ;)
Where's my Droid does that and is the best free app on the market:

I'm sorry, my answer above assumes you have some other way SIP or Google Voice to send an SMS, which you would have already had setup!
I'm not aware of any app that does this without initiation from an SMS. Sorry.
