Download the PDA.tar you want to modify
Extract the four files of PDA.tar.md5 in a directory.
Copy the four files in SD card of Phone
preferably name it mnt
so all four files should lie in mnt /sdcard/mnt
Fire up adb/Terminal emulator
#busybox mount system.rfs mnt2
use the file explorer like default My files/Astro/AND explorer/Root Explorer/ES file explorer.
modify the apps you want to add or remove in /system/mnt/mnt2/app
after modifying apps, fire terminal
#tar -c boot.img recovery.img system.rfs data.rfs >> PDA.tar
#md5sum -t PDA.tar >> PDA.tar
#mv PDA.tar PDA.tar.md5
