+/**
+ * A quick n' dirty hack to fix a dying GrowlVoice
+ *
+ * GrowlVoice is now officially dead: https://twitter.com/GrowlVoice/status/455931023868448768
+ * However, Google didn't really shut off API access (there wasn't really any to begin with);
+ * they slightly mangled a JSON object GrowlVoice was looking for on one of Google Voice's
+ * internal pages.
+ *
+ * The following is a Cycript script that will bring a dead GrowlVoice back
+ * to life for the moment (until Google decides to mangle things more).
+ *
+ * To use:
+ *
+ *  - Download cycript from cycript.org, and extract somewhere sane
+ *  - download this script to the same place as cycript
+ *  - Start GrowlVoice (it will complain about malformed JSON)
+ *  - Run ./cycript -p GrowlVoice fix_growlvoice.js

+
+// It's failing in accountInfoFetcher:finishedWithData:error:, a callback method
+// that parses a response from Google's auth page, and pulls in a bunch of info.
+//
+// Since it's failing there, let's hook it, and massage the data we're getting
+// back until GrowlVoice can understand it again.
+//
+// Using MobileSubstrate, the following line 'swizzles' the method, replacing 
+// it with our own wrapper function:
+MS.hookMessage(GoogleVoiceLoginInterface, MESSAGE, function (fetcher, data, err) {
+  // In particular, we need to find a json object embedded in the page that was
+  // just returned into this function (as the second arg, data).
+
+  // Convert to NSString from NSData
+  var sdata = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
+
+  // Find the start and end of the JSON object, then split the page into 3
+  // sections: before the json object, after, and the object itself. This is 
+  // pretty fragile, but exactly what GrowlVoice does, so we might as well be 
+  // consistant.

+  var prefix = sdata.slice(0, startIndex);
+  var suffix = sdata.slice(endIndex);
+  var authJSON = sdata.slice(startIndex, endIndex);
+
+  // Now, fix the JSON object.  This method is robust, but dangerous:
+  // Google's new JSON encoding format only works when evaluating as a
+  // javascript statement -- it's really not even close to valid json.
+  // Therefore, we evaluate that line as a javascript statement, then
+  // re-encode back to well-formed json.
+  eval('var gcData = ' + authJSON);

+  oldm->call(this, fetcher, newdata, err);
