My current setup is Dropbox with a directory called /Docs, in which I have my emacs .org outline files.
If you don't know about Emacs and org-mode, these files are plain text, just formatted with ** and so on for headings, however the extension is .org
I have tried Elements, however it would not let me view notes with the extension of .org
So essentially, I want to sync up notes between org-mode and an app on my iPhone 4, without using MobileOrg (which doesn't really sync as such).
