My bookmarks on my iPhone 4 with iOS6 are stuck in sync. I cannot delete them, and I cannot add to or delete from my reading list. I unchecked, signed out, and deleted the iCloud control panel, I turned off syncing bookmarks on iTunes, and I turned off syncing with iCloud bookmarks on my iPhone. Is there any other option I have to fix this issue without restoring and setting up as new? I feel like it could be the source of my battery drain as well.
