With the release of the recent Tizen 2.2 SDK there is also a release of new firmware to download and flash for the Tizen Developer Device RD-PQ 2.2_20130719.3_RD-PQ.tar.gz.

The download is available from the following location: http://download.tizen.org/releases/2.2/tizen-2.2/images/RD-PQ/

I haven’t noticed anything substantially different. It will be interesting to see if you do?
