Is there a WebRequest alternative in Unity-IPhone?

I’m in a need of writing some scripts making a synchronous HTTP web request using some http-prefixed url synchronously. But it seems that the System.Net.WebRequest class works well in the Unity Editor only, but not on the iOS device. Is there any advisable alternative? I really don’t want to use the native library such as AsiHttpRequest or NSblahblah. Any suggestion would be appreciated.

My survey gives negative answer to this one. You may have to use a native library instead if you have such a request.
