The current SDK does not support multiple radio interfaces at the same
time. This means you cannot be on cellular and at the same time use
Wifi for Data connectivity. I agree that it would be nice if it would
be supported. Of course you still can change the underlying framework
and native code to support this functionality.

Looking at the current set of APIs on SDK level you won't be able to
write an app with the settings you described. It would be great if the
Android team would extend the telephony/radio interface APIs to offer
such functionality (which can be found in other TAPI implementations).
