-5) Optional API: Registered handlers
-
-This lets you register named handlers for e.g. command handling. You should register handlers 
-
-*Note:* You need to 1) register ObjC handlers before loading the UIWebView, and 2) register javascript handlers before calling `WebViewJavascriptBridge.init`.
-
-In ObjC:
-	
-	// Register handler
-	[javascriptBridge registerHandler:@"greetPerson" handler:^(id responseData, WVJBResponseHandler callback) {
-		callback([NSString stringWithFormat:@"Hello, %@", [data objectForKey:@"name"]]);
-	}];
-	// Call javascript handlers
-	[javascriptBridge callHandler:@"showAlert" data:@"FooBar"];
-	[javascriptBridge callHandler:@"getUrl" data:nil callback:^(id data) {
-		NSLog(@"UIWebView url is %@", data);
-	}];
-
-In javascript:
-	
-	// Register handlers
-	WebViewJavascriptBridge.registerHandler('showAlert', function(data) {
-		alert(data)
-	})
-	WebViewJavascriptBridge.registerHandler('getUrl', function(data, responseCallback) {
-		responseCallback(document.location.toString())

-	// Call ObjC handler
-	WebViewJavascriptBridge.callHandler('greetPerson', { name:'Marcus' }, function responseCallback(data) {

 iOS4 support (with JSONKit)
 ---------------------------
 
-	WebViewJavascriptBridge uses `NSJSONSerialization` by default. If you need iOS 4 support then you can use [JSONKit](https://github.com/johnezang/JSONKit/), and add `USE_JSONKIT` to the preprocessor macros for your project.
+*Note*: iOS4 support has not yet been tested in v2.
