So to clear things up for people who stumble across this question,

The best way to achieve what the OP wants is with the following code:

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    DataGridViewCheckBoxCell cell = row.Cells[0] as DataGridViewCheckBoxCell; 

    //We don't want a null exception!
    if (cell.Value != null)
    {
        if (cell.Value == cell.TrueValue)
        {
           //It's checked!
        }  
    }              
}
