Is there any way to erase personal information from my phone that has already been stolen? My phone has been stolen. I do not want the thief to have access to any of my personal information such as calls, texts, and information saved in the phones contents. Is there any possible way I can get this information erased from my phone?
As long as your phone still has battery power left and is still switched on and connected to the phone networks, you can use one of the phone wiping apps that specifically advertise that they can be remotely installed and used after the phone is stolen.

From a quick search of the Android Market, there are PlanB that is designed for this purpose:


  Plan B is the 'find my phone' app that
  you download AFTER you lose your
  phone.
  
  Plan B is your last resort to find
  your missing phone.
  
  This is the first and only 'find my
  phone' app that you download AFTER
  you've already lost your phone. Having
  Lookout on your phone is the best way
  to protect your phone and find it
  fast, but use Plan B if you have
  already lost your phone and didn't
  have Lookout installed.


And Phonelocator Pro is one that advertises this:


  
  Can be installed after the phone was lost. Install this application to your
  phone from the web Android Market
  remotely. Send the "PLlocator" word to
  your phone, in a text message. It will
  respond back with the phone position.
  The word is case sensitive, so be sure
  you send this exact word "PLlocator"
