Any word on the Sibley app for smartphones? I don't want to shell out $20 if they're going to create a whole new one.

Here's a response from Sibley to a question posed on his blog:

"........ Yes, we are working on getting the app ready and hope to have it available in March when the new book is out. Discussions about pricing are ongoing, and all options are still under consideration."

Thanks! I somehow missed that.
