Keep pressing the widget/icon in your DROID home page for long. You can see a trash bin appear at the bottom of your home page. Once you see the TRASH bin, drag and drop the widget/icon into Trash........... DONE.
Not Sure if the delete widget/icon goes into a Android recycle bin or gets purged completely. May I should connect to pc after deleting and check if a recycle bin / folder is present in 16GB microSD.
