UPDATE (10/06/2011): I started an online version of the script, see new blog post.
For a while I’ve been checking out various programs for extracting and converting text messages from the iPhone SMS storage SQLite database. For some reason they seem to be either for purchase or not doing their job well.
When I found out that all they are doing is pretty much just some simple SQL query and putting the result into various output formats, I decided to quickly write this myself, while keeping it simple and open.
