They no longer include Maemo in the default set of tools provided in the SDK, but it should still be available through the package manager. That's how I got it, anyway. Here's how:

- In Qt Creator, go to the help menu and select "Start Updater"

- The Qt SDK Setup Wizard dialog should appear. In that window, click on the "Package manager" option and hit Continue. (It should be the first option on the list.)

- A tree selector widget will appear; in it, you need to open first "Qt SDK" and then beneath that "Development Tools". Under Development Tools you'll find "Maemo Toolchain" (among a variety of other interesting items). Hit the checkbox next to that, then hit Continue, and you should get the full Maemo package.
