How can I make my phone/tablet ring remotely without a SIM card? 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.


this is the app you can use to control/wipe/access info about your lost device, yadayada


Give it a little time to install to your device, then install AndroidLost Jumpstart from the online Google Play Store as well


  This app will wake up the registration process on the androidlost app
  when ever a phone call is made, an SMS received, battery is low, a
  package is added, removed or changed.


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 ;)

I haven't tested this yet, but I will as soon as I can I tested this on my own phone (although the page for Jumpstart only specifies tablets), and it works! It says it will register on SMS or app install, I did both first, and the activation worked. This is an awesome utility.
