+    \section2 Supported Configurations
+
+    When you select the Qt version to build the application with, consider
+    which version provides the application with the widest support on different
+    Symbian platforms. The binary compatibility promise of Qt and Symbian means
+    that applications that are built against Qt 4.6.3 also run on Qt 4.7.3.
+    Similarly, applications that are supported on Symbian^1 are also supported
+    on Symbian^3. However, dependencies, such as QML or Qt Mobility API
+    versions might restrict the choice of Qt versions that you have.
+
+    In general, if you use only Qt widgets and APIs in the application, you
+    can use \gui {Qt 4.6.3 for Symbian^1} to build it.
+    The application is supported on both Symbian^1 and Symbian^3 devices.
+
+    If you use QML in the application, you can use \gui {Qt 4.7.3 for
+    Symbian^1} to build it. The application is supported on both Symbian^1 and
+    Symbian^3 devices.
+
+    If you use native Symbian APIs, you must check that they are available on
+    the target devices. For more information about the API differences between
+    Symbian^1 (S60 5th Edition) and Symbian^3, see the \bold {Symbian
+    Reference Documentation for Qt}, which is delivered together with \QSDK
+    and which you can view in the \gui Help mode.
+
+    The following table summarizes the supported configurations for each Qt
+    version available in Qt Creator build settings:
