Situation with D on iOS, Android, and WP8?

[Mitchell via Digitalmars-d]

I've seen a few posts similar to this but they were quite old and 
probably have outdated information, so I'd like to ask again - 
what is the situation with D on the major mobile platforms?

Not really concerned with C#/Obj-C/Java interop, more just if you 
can compile a hello world using Phobos on it.

Thanks,
Mitchell
