I've seen other apps are using a round icon for closing a view. The only similar icon I found is UIBarButtonSystemItemStop. But this presents only a rotated cross with a border (as always with buttons) around it. I rather would like have something like a UIButtonTypeInfoLight. If this button is used, no border is visible. Also the icon ...

It is clear that Mono Touch is part of the solution as it allows C# code to run on the IPhone, however Mono Touch wraps the IPhone API so does not provide a common API.
