WARNING: Using legacy cell layout due to delegate implementation of tableView:accessoryTypeForRowWithIndexPath

tableView:accessoryTypeForRowWithIndexPath: is deprecated in iPhone OS 3.0 with the following note:

Use the accessory-view and accessory-type properties (for both normal and editing modes) of the UITableViewCell class when configuring table-view cells.

They mean you should set accessoryType/accessoryView properties in tableView:cellForRowAtIndexPath: instead.
