One thing to also mention is you cannot reference .NET assemblies that haven't been built/compiled using the .NET MonoTouch configuration.

So if you have a favourite .NET 2.0 library you will need to re-import the source into a new MonoTouch project, compile it, and then reference it. There may be an easier way of doing this by editing the .csproj file but I haven't found it.
