title: Is it possible to identify the carrier / operator (ATT, Verizon, etc.) from the Android User Agent String
body: <p>Server Side I need to identify the carrier (ATT, Verizon, etc.).</p>
  
  <p>On iPhone you can do it with the firmware number.  I was thinking that Android's device + build information in the UA might do the trick.</p>
  
  <p>Has anyone done this.  I do not have client side access so Telephony Manager is not an option.</p>
