Happened to me too. : (
I took the release notes' advice and spent a few hours this morning making my apache server do WebDAV.. I synced my database to it, they went up there just fine..
I then ran the update and my database was gone. (which is ok, as I had a backup)
The problem is now I can't get OF to sync my old database back to my iphone. It goes through the entire sync progress bar, downloads all the files (I watched the logs) then it goes to an 'opening document' progress bar, I see a single tiny tic, and it goes back to the home screen. None of my tasks are there.
: (
I've gone through this process a few times, always with the same results.
anyone have any ideas? I have a folder full of zip files, which contain a bunch of tiny xml snippets about my tasks/projects..
