The default browser on my Galaxy S Vibrant running Froyo has a bunch of favorites pre-loaded -- CNN, Facebook, etc. The browser tells me they can't be deleted when I try. How can I delete them? Is there a folder of them somewhere I can just delete? I am rooted.
Doing a full
Clear Data on the default browser ("Internet" on the Incredible) worked for me. Just make sure you have your other bookmarks backed up (for example, using an app such as Backup Bookmarks could be used to back them up to SD). The steps should look something like this:
Settings > Applications > Manage Applications > All > Internet > Clear Data
EDIT: As mentioned in the comment below, Bookmarks Manager allows users to delete the default browser favorites/bookmarks. Note that the crossed-out portion of this answer would erase things such as history, entered text, etc. however, apparently not the default bookmarks.
