hi, just curious to know which miniSD is /dev/mmcblk0p3?
It seems that I only copied the root file system to the external SD card, and it works now. So it seems that /dev/mmcblk0 be the external minisd? Or does the kernel has the capability to try different miniSDs?

NITdroid is far better in functionality and usability! the clock is working, the gui is pretty fast! The stability is the only thing needs to be improved. Every time i tried to enable the wifi, it restarts the GUI. And I observed frequent reboot after some time idle.
