The new firmware for PDN is good.
Now the CPU is running at
800MHz which I think Samsung smdk6410 has mentioned in datasheets, so no need to overclock using setCPU.
Also as "gadgetrants" mentioned the screen response is much better now, wifi is a little more stable as compared to 7/18 firmware (in the wifi settings page) click vol+ button to get the menu and then in settings click on "Never sleep").
Android market is accessible after doing the androidId hack.
