I get excited about some very boring things sometimes, but today I read about this about an upcoming Laridian PocketBible for iPhone update:

The major new feature is notes. You can associate notes with any Bible verse. Notes are independent of the Bible you’re reading. So a note on John 3:16 in the KJV also shows up on John 3:16 in the NIV.

Notes are indicated by a “Note” link at the start of the verse. Tap the link to view the note, or simply tap-and-hold anywhere on the verse to open the context menu and from there, choose to view or create a note.

Any references to Bible verses in your notes will be automatically linked. While viewing a note, just tap the reference to view the Bible verse. Notes are happy to be just plain text, but if you’re comfortable with HTML you can use most HTML tags in your notes. We provide a menu of HTML tags you can easily insert, and bold and italics are available from a toolbar in the note editor. So select the word you want to italicize, then use the <i> button to italicize it. No advanced HTML tagging knowledge required.

The note editor supports undo and redo. Few iPhone apps do, and for good reason. The current state of the text editing features on the iPhone is pretty primitive. It’s difficult to get access to everything you need to support undo/redo.

That will be great.  Of course their competitors at Olive Tree are doing some really exciting things with notes and syncing with Evernote.  Also Mantis Bible has some form of note syncing and their web site.  Both are still very much in “beta”.

The update to Laridian’s software will be coming in a few weeks.  When it does it will also add rotation lock, copy/paste of passages and verses to other apps, and some bug fixes.
