title: UITableViewCellSeparatorStyleNone doesn't work with UITableViewStyleGrouped
body: <p>To hide separators in a UITableView, setting the separatorStyle property to UITableViewCellSeparatorStyleNone works fine if the table style is UITableViewStylePlain. But, for me at least, it doesn't work if the table style is UITableViewStyleGrouped. Has anyone else seen (and hopefully solved) this problem?</p>
