Change Files on Droid 2

After rooting the Droid 2, there are sometimes files you want to change. You can pay for the Root Explorer app or use the free Android Terminal Emulator with linux commands on your phone. To change the system folder and below from read-only to read-write, do the following:

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblk3 /system
rm /system/app/Gmail.apk
reboot
