Easy way to get *all* Notes to synchronize via iCloud?

You need a 10.6/10.7 system handy as this doesn't work in 10.8. The method I've previously used is as follows:

• Plug your iPhone into your Mac and go into iTunes -> Your Device -> Info tab and choose to Sync notes.

• This should grab the notes out of the On my iPhone section and dump them into Mail.app.

• Your notes should appear under the Notes section in Mail.app, but ideally filed under an On My Mac header.

• Simply select all the notes from under On My Mac and drag them into the iCloud section. That should upload them all to iCloud and save you some time copying and pasting or fiddling with other software!

This is actually amazingly simple in Mountain Lion.

• Open the Notes app.

• You should have a list of notes folders on the left side.

• Select the "On My iPhone" folder or whichever folder you want to move notes from.

• Then select all the notes using Command+A.

• Drag them to the Notes folder in iCloud.

I literally just did this about 5 or so minutes ago.

Hope this helps. :-)

You can use a Mac app like PhoneView to access the notes on your iPhone. You will still have to copy and paste, but that can be a much faster process on the Mac—you have all sorts of options to speed things up, from keyboard shortcuts to AppleScript.
