Alongside today's EVO 4G leak, a Gingerbread test ROM for the HTC Desire has also leaked out via the 911HTC blog. Version 3.06.707.0 is based on Android 2.3.3, but is running the old version of Sense, which will come as disappointing news for Desire owners hoping to get their hands on the new-fangled Sense 2.0 found on more recent handsets.
Right now the ROM (pre-rooted, of course) is available as a flashable zip courtesy of XDA member robocik. Upon initial inspection, we noticed the clock widget animations and "fast boot" feature from Sense 2.0 have been ported across, and there seem to be some minor UI changes in the browser too.
Flashing an unofficial leaked ROM like this should always be approached with caution. If you decide to take the plunge, remember that this ROM is intended for GSM Desires from Europe and Asia -- it won't work on the U.S. Celular CDMA version of the phone. [XDA, 911HTC]
