UITableView.backgroundColor in SDK 4.0

Question

I have an app that has a custom background for a UITableView. Up to the SDK 3.1.3 this was done by setting the table's backgroundColor property to [UIColor clearColor] and placing the table on top of another view (a UIImageView' for example). SDK 3.2 added thebackgroundViewproperty, and the same effect could be achieved by setting it tonil`.

SDK 4.0 removed all traces of SDK 3.1.x libs, so it is impossible to compile a 4.0-compatible version that still works on 3.1.x devices.

If I create in SDK 3.2 an ad-hoc version and install it via iTunes on a 4.0 device, everything is fine, the app works as expected and the world is happy. If I compile it on the SDK 4.0 it does not, even if I set the target to 3.0 and call setBackgroundColor: (so the compiler doesn't complain about a non-existant symbol).

So, is there any solution for this? I basically want to: - compile with the SDK 4.0 (so I can test the app with a 4.0 device) - make it work on 3.x devices - use 3.1.x symbols, deprecated on 4.0, since the installed base is still huge

Ok, I just weak-link UIKit.framework as stated in this question: http://stackoverflow.com/questions/2954342/recommended-way-to-support-backward-forward-compatibility-in-iphone-app and conditionally call the appropriate method with UI_USER_INTERFACE_IDIOM()
