What is the most secure way to connect to a WCF Service from monodroid?

Question

I have a WCF Service which I need to call from a monodroid app. I want to prevent users from using a tool like fiddler to read the data. I tried using TLS with server- and clientcertificates but it seems that monodroid doesn't support clientcertificates. Is there another option I could try to secure the service?

Edit: To clarify the question: I'm looking for a possibility to encrypt the communication between the app and the service to prevent man in the middle attacks like using fiddler or another proxy. The best thing I found so far is using a basicHttpBinding with transport security and a server certificate but this doesn't work against man in the middle attacks.
