Yeah… Thanks to xda-developer, skink123. He made a ClockworkMod Recovery + A2SD+ EXT3 partition ROM based on prj Clean Desire v0.3.2. So you can install it with your SD card through ClockworkMod Recovery method and no worry about not enough internal storage space because application data is stored on ext3 partition on SD card. By the way, it is based on Android 2.2 Froyo and using prj v0.4 Kernel.
