Had a bit of an issue that took me a bit of head scratching. I had a UITableView which worked perfectly in iPhone API 2.2 but in 3.0 the insert/delete icons weren’t being displayed. Reworked and checked all the code but nothing worked.

It seems if you set the editing flag to YES when creating the tableViewCell’s, the insert/delete icon applied by the table delegate (editingStyleForRowAtIndexPath) isn’t displayed. Removing the call to cell.editing seems to fix the problem. This seems to be one of those things that is slightly different between iPhone OS 2.2 and 3.0.
