Here is how I did it. I just followed Teddy's example above and simplified it. I have one question though, why even bother with the refresh on the DELETES?

  public static bool UndoPendingChanges(this NtsSuiteDataContext dbContext)
  {
     if (dbContext.ChangesPending())
     {
        ChangeSet dbChangeSet = dbContext.GetChangeSet();

        dbContext.Refresh(RefreshMode.OverwriteCurrentValues, dbChangeSet.Deletes);
        dbContext.Refresh(RefreshMode.OverwriteCurrentValues, dbChangeSet.Updates);

        //Undo Inserts
        foreach (object objToInsert in dbChangeSet.Inserts)
        {
           dbContext.GetTable(objToInsert.GetType()).DeleteOnSubmit(objToInsert);
        }

        //Undo deletes
        foreach (object objToDelete in dbChangeSet.Deletes)
        {
           dbContext.GetTable(objToDelete.GetType()).InsertOnSubmit(objToDelete);
        }
     }

     return true;
  }
