iPhone 4 compatible with iPad keyboard dock. Possible?

Well now that iOS 4 has bluetooth keyboard technology, is it possible to use iPhone 4 on the iPad Keyboard Dock? Obviously nobody will really know. But anyone has an idea or possibly of how to make it work? Did it work with the 3GS?

 

yes, apparently so

It kind of works, but it doesn't fit like the 3G(S) did. You have to press it in too hard and it feels like you could break the dock connector.

 

Does the iPad keyboard connect to the iPhone with Bluetooth or a wired connection via the dock connector? Many people like myself are looking for a physical keyboard they can use on an airplane, but Bluetooth is not allowed in air.
