As before, unzip and copy the folder to this location, replacing the one that's there:
/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Project Templates/Application/Navigation-based Application/
Note: I updated the project yet again, at 1:11 pm Eastern time, to deal with a problem with inserting the first object when using a section name key path. Because tables can't have zero sections, this new version checks to make sure before inserting a new section, that it isn't an empty table getting its first row. In that case, the table will already have one section and doesn't need a second. Adding a second in that scenario causes a crash.
Note Again: Another update to the project at 10:21 eastern time on November 11. Fixed a few more issues I found. I hope this will be the last version.
Note Yet Again: I forgot to move the update into the right folder on the web server, so the 10:21 eastern time update actually happened at 10:59. Re-download if you grabbed it between those times.
Thanks to Simon Wolf for catching it
