How do I delete apps using Terminal Emulator???
Open up terminal emulator:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd (You will change to whatever directory the app is in, most likely: /system/app)
ls (if you can't remember the name of the app, this will list them all)
rm (enter the name of the app exactly, caps and all ex: com.Email.apk)
mount -o remount,ro -t yaffs2 /dev/block/mtdblock4 /system
Exit Terminal emulator and reboot phone.
Or, you could use supermanager with root access, which is what I usually do.
