+// determining low-bandwidth via navigator.connection
+
+// There are two iterations of the navigator.connection interface:
+
+// The first is present in Android 2.2+ and only in the Browser (not WebView)
+// : docs.phonegap.com/en/1.2.0/phonegap_connection_connection.md.html#connection.type
+// : davidbcalhoun.com/2010/using-navigator-connection-android
+
+// The second is specced at dev.w3.org/2009/dap/netinfo/ and perhaps landing in WebKit
+// : bugs.webkit.org/show_bug.cgi?id=73528
+
+// unknown devices are assumed as fast
+// for more rigorous network testing, consider boomerang.js: github.com/bluesmoon/boomerang/
+
+Modernizr.addTest('lowbandwidth', function() {
+
+  var connection = navigator.connection || { type: 0 }; // polyfill

+      connection.type == 4 || // connection.CELL_3G
